Scaling Nanoribbon Transistors with Monolayer Transition Metal Dichalcogenides
Tara Peña, Anton E. O. Persson, Andrey Krayev +13
Nanoscale transistors require aggressive reduction of all channel dimensions: length, width, and thickness. While monolayer two-dimensional semiconductors (2DS) offer ultimate thic…
Excitation laser energy dependence of the gap-mode TERS spectra of WS and MoS on silver
Andrey Krayev, Eleonora Isotta, Lauren Hoang +8
We present a systematic study of the dependence of gap mode tip-enhanced Raman scattering (TERS) of mono- and bi-layer WS and MoS as a function of excitation laser energy.…
Highly tunable room-temperature plexcitons in monolayer WSe2 /gap-plasmon nanocavities
Thomas P. Darlington, Mahfujur Rahaman, Kevin W. C. Kwock +16
The advancement of quantum photonic technologies relies on the ability to precisely control the degrees of freedom of optically active states. Here, we realize real-time, room-temp…
Photoconductive Effects in Single Crystals of BaZrS
Boyang Zhao, Huandong Chen, Ragib Ahsan +11
Chalcogenide perovskites, such as BaZrS, are emerging semiconductors with potential for high photovoltaic power conversion efficiency. The role of defects in the efficiency of…
Metallic vs. Semiconducting Properties of Quasi-One-Dimensional Tantalum Selenide van der Waals Nanoribbons
Fariborz Kargar, Andrey Krayev, Michelle Wurch +7
We conducted a tip-enhanced Raman scattering spectroscopy (TERS) and photoluminescence (PL) study of quasi-1D TaSe3 nanoribbons exfoliated onto gold substrates. At a selenium defic…
Nanoscale Optical Imaging of 2D Semiconductor Stacking Orders by Exciton-Enhanced Second Harmonic Generation
Kaiyuan Yao, Shuai Zhang, Emanuil Yanev +9
Second harmonic generation (SHG) is a nonlinear optical response arising exclusively from broken inversion symmetry in the electric-dipole limit. Recently, SHG has attracted widesp…
