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…
