Deep-Learning-Enabled Fast Optical Identification and Characterization of Two-Dimensional Materials
Bingnan Han, Yuxuan Lin, Yafang Yang +22
Advanced microscopy and/or spectroscopy tools play indispensable role in nanoscience and nanotechnology research, as it provides rich information about the growth mechanism, chemic…
Light-Induced Charge Density Wave in LaTe
Anshul Kogar, Alfred Zong, Pavel E. Dolgirev +18
When electrons in a solid are excited with light, they can alter the free energy landscape and access phases of matter that are beyond reach in thermal equilibrium. This accessibil…
Dynamical slowing down in an ultrafast photo-induced phase transition
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +20
Complex systems, which consist of a large number of interacting constituents, often exhibit universal behavior near a phase transition. A slowdown of certain dynamical observables…
Internal nanostructure diagnosis with hyperbolic phonon polaritons in hexagonal boron nitride
Siyuan Dai, Mykhailo Tymchenko, Zai-quan Xu +10
Imaging materials and inner structures with resolution below the diffraction limit has become of fundamental importance in recent years for a wide variety of applications. In this…
Enhanced Superconductivity and Suppression of Charge-density Wave Order in 2H-TaS in the Two-dimensional Limit
Yafang Yang, Shiang Fang, Valla Fatemi +6
As superconductors are thinned down to the 2D limit, their critical temperature typically decreases. Here we report the opposite behavior, a substantial enhancement of …
Manipulation and steering of hyperbolic surface polaritons in hexagonal boron nitride
S. Dai, M. Tymchenko, Y. Yang +8
Hexagonal boron nitride (hBN) is a natural hyperbolic material that supports both volume-confined hyperbolic polaritons (HPs) and sidewall-confined hyperbolic surface polaritons (H…
Relative efficiency of polariton emission in two-dimensional materials
Siyuan Dai, Qiong Ma, Yafang Yang +15
We investigated emission and propagation of polaritons in a two dimensional van der Waals material hexagonal boron nitride (hBN). Our specific emphasis in this work is on hyperboli…
Self-aligned local electrolyte gating of 2D materials with nanoscale resolution
Cheng Peng, Dmitri K. Efetov, Sebastien Nanot +8
In the effort to make 2D materials-based devices smaller, faster, and more efficient, it is important to control charge carrier at lengths approaching the nanometer scale. Traditio…
Optoelectronics with electrically tunable PN diodes in a monolayer dichalcogenide
Britton W. H. Baugher, Hugh O. H. Churchill, Yafang Yang +1
One of the most fundamental devices for electronics and optoelectronics is the PN junction, which provides the functional element of diodes, bipolar transistors, photodetectors, LE…
