研究文章標題：Electrically tunable correlated domain wall network in twisted bilayer graphene
研究重點簡述：We investigated nanoscale systems consisting of two sheets of graphene, each a single-atom-thick layer of carbon. When these graphene sheets are stacked with a slight misalignment and a vertical electric field is applied, the electrons form a triangular network within the 2D structure. We explored how the properties of the electronic network vary with the misalignment angle, the applied electric field, and the device geometry.

以下為徐博士對於在 IOP Publishing 發表 OA 文章的感想與建議
Do you have any personal motivation for studying this topic?
My motivation for this research is that electrons in low dimensions are known to behave very differently from those in higher dimensions. This topic provides another platform for such behavior. Recall that we are working with a nanoscale system composed solely of carbon atoms, one of the most abundant elements on Earth. Yet, through careful design, we can achieve superconductivity—an electronic state with zero resistance!
How easy was it to publish open access under the transformative agreement?
I remember just ticking some boxes—yes, it was as simple as that.
Why did you decide to publish the research open access?, Why do you think it’s important to be able to publish open access, What benefits did you see from publishing your work open access?
I want to share our research with as many people as possible. Open access publishing achieves this by removing barriers related to finances, institutional affiliations, identity, and location.
Would you recommend publishing under a Transformative Agreement to other authors in your field?
Yes. Open access (OA) is the new trend in research. Publishing OA articles through Transformative Agreements not only waives direct costs for authors but also promotes collaboration among publishers, research institutes, and funding agencies.

研究文章標題：Large-area and few-layered 1T′-MoTe2 thin films grown by cold-wall chemical vapor deposition
研究重點簡述：We used a special technique called cold-wall chemical vapor deposition to grow very thin layers of a material called molybdenum ditelluride (MoTe2) on sapphire wafers. This was done in two steps, using molybdenum oxide (MoO3) and tellurium (Te) powders under low pressure.
The MoTe2 layers that we produced mostly have a specific structure known as the 1T’ phase. This phase is identified by a particular Raman peak at 161~163 cm^-1. We were able to achieve this 1T’ phase by carefully controlling the temperature during the second step of the growth process.
The thickness of these MoTe2 layers can be precisely controlled between 3.5 and 5.7 nanometers (very thin!). We measured this using atomic force microscopy.
When we tested the electrical properties of these layers, we found that they conduct electricity well, with a hole concentration of 7.9 x 10^21 cm^-3 and a mobility of 0.2 cm^2/Vs.
To make electrical connections to these thin layers, we used a combination of titanium (Ti) and aluminum (Al) metals. We found that the resistance at the contact between the metal and the MoTe2 layer was very low, around 1.0 x 10^-4 Ω-cm^2. This is a promising result for future applications of 2D materials like MoTe2.

研究文章標題：Investigation of the Activation and Diffusion of Ion-Implanted p-Type and n-Type Dopants in Germanium Using High-Pressure Annealing
研究重點簡述：The research focuses on investigating the effects of high-pressure annealing (HPA) and microwave annealing (MWA) on the activation of ion-implanted dopants (phosphorus and boron) in germanium. The main objectives include:
1. Comparing the performance of HPA and MWA in suppressing dopant diffusion.
2. Evaluating the effectiveness of these techniques in reducing sheet resistance and enhancing carrier concentration and mobility.
3. Exploring solid-phase epitaxial regrowth (SPER) behavior to improve the crystalline quality of germanium-based devices.
4. Determining optimal process conditions to balance high-temperature activation and dopant diffusion suppression.
The study reveals that HPA outperforms MWA in achieving higher dopant activation rates and better diffusion suppression, especially under high-temperature conditions, demonstrating significant potential for germanium-based device fabrication.

研究文章標題：Nonlocal correlations in quantum networks distributed with different entangled states
研究重點簡述：We explore the correlation strengths in asymmetric quantum networks. Therein, the independent quantum sources can emit variant entangled states. In this work, the nonlinear Bell inequalities tailored to the distributed entangled states are proposed. The algebraic maximal violations of the proposed nonlinear Bell inequalities can be realized within the quantum region. We demonstrate how to implement the segmented Bell operators in the Bell tests. Furthermore, we devise the fitting Bell operators using the sum-of-square approach.

研究文章標題：Consistency of the Bayes method for the inverse scattering problem
研究重點簡述：In this work, we consider the inverse scattering problem of determining an unknown refractive index from the far-field measurements using the nonparametric Bayesian approach. We use a collection of large ‘samples’, which are noisy discrete measurements taking from the scattering amplitude. We will study the frequentist property of the posterior distribution as the sample size tends to infinity. Our aim is to establish the consistency of the posterior distribution with an explicit contraction rate in terms of the sample size. We will consider two different priors on the space of parameters. The proof relies on the stability estimates of the forward and inverse problems. Due to the ill-posedness of the inverse scattering problem, the contraction rate is of a logarithmic type. We also show that such contraction rate is optimal in the statistical minimax sense.

以下為教授對於在 IOP Publishing 發表 OA 文章的感想與建議
Do you have any personal motivation for studying this topic?
The deterministic inverse problem has been well studied. However, the uniqueness result only can guaranteed by infinitely many measurements, which is not feasible. One feasible approach is to collect large numbers of measurements, and this strongly suggests probabilistic approaches.
How easy was it to publish open access under the transformative agreement?
The publication process is exactly the same as before I did.
Why do you think it’s important to be able to publish open access?
Not only to follow the Plan S in European Union, it is also very helpful if the paper is accessible.
Would you recommend publishing under a Transformative Agreement to other authors in your field?
Yes, of course.

研究文章標題：Design and analysis of an extended buckled beam piezoelectric energy harvester subjected to different axial preload
研究重點簡述：In this paper, a piezoelectric energy harvester composed of a buckled beam and an extended beam with a tip mass is proposed. This study develops a mathematical model and a prototype of the energy harvester. The performance of the energy harvester is influenced by the axial load applied at the end of the buckled beam. Under an axial force below the critical load, the energy harvester exhibits a pre-buckling state with a hardening nonlinear characteristic. Conversely, when the axial force exceeds the critical load, a post-buckling state with a softening nonlinear characteristic is observed. Simulation results are validated through experiments, and the relationship between axial displacement and axial force is obtained through experimental data. Moreover, increasing the tip mass enhances the output voltage under the same acceleration. The energy harvester demonstrates superior performance in terms of output power and strain distribution compared to a cantilever counterpart.

研究文章標題：The cosmological collider in R^2 inflation
研究重點簡述：Cosmic Inflation is a theory for the very beginning of Big Bang cosmology. Inflation provides solutions to the Horizon problem (why the observed Cosmic Microwave Background (CMB) radiations are statistically homogeneous and isotropic?) and the flatness problem (why the geometry of our Universe is just Euclidean?) from our observations. More recent precision measurements on the CMB anisotropy and the large scale structure of galaxies have confirmed initial conditions of the matter or radiation density fluctuations are highly consistent with the theoretical predictions of inflation.
R^2 inflation, as proposed by the renowned cosmologist Alexei Starobinsky in the 1980’s, has become the best-fit model among all theories of inflation according to reports from the precision measurements of the CMB via the Planck satellite. The so-called “cosmological collider” is a relatively new theoretical concept developed in the 2010’s which identifies the particular observational imprints for searching for new particles created during inflation. Given that the temperature at the primordial epoch of our Universe can be very very high, it is theoretically possible to use the cosmological collider to find out new particles at energy scales beyond the limitation of ground based particle colliders.
In this paper, I showcase how those “imprints of new particles” shall look like in the R^2 inflation model for the cosmological collider program.
