Nonlinear Photocurrent Spectroscopy and Polarization-Tunable Shift Current in the Layered Semiconductor
Alexander M. Blackston, Md Kazi Rokunuzzaman, Ryan P. Siebenaller +4
The class of layered metal thiophosphates and selenophosphates are emerging as promising candidates for non-linear photonic and optoelectronic applications. Here we report one-phot…

Photoluminescence excitation spectroscopy of quantum wire-like dislocation states in ZnS
Alexander Blackston, Alexandra Fonseca Montenegro, Sevim Polat Genlik +2
Recent \textit{ab initio} calculations predict 1D dispersive electronic bands confined to the atomic scale cores of dislocations in the wide bandgap (3.84 eV) semiconductor ZnS. We…

Ferroelectric Epsilon-WO3 Nanoparticles and Its Bipolaron Driven Opto-electronic Properties at Room Temperature
Mohammad M. Rahaman, Jose Flores, Mohamed Y. Noor +6
A unique polymorph of binary tungsten trioxide, the epsilon phase of WO3, has non-centrosymmetric ferroelectric structure, typically stable below -43 degree C in bulk. We have stab…
