Lasing and Amplification from Two-Dimensional Atom Arrays
Vahagn Mkhitaryan, Lijun Meng, Andrea Marini +1
We explore the ability of two-dimensional periodic atom arrays to produce light amplification and generate laser emission when gain is introduced through external optical pumping.…
Direct and quasi-direct band gap silicon allotropes with remarkable stability
Chaoyu He, Jin Li, xiangyang Peng +3
In our present work, five previously proposed sp carbon crystals were suggested as silicon allotropes and their stabilities, electronic and optical properties were investigated…
Simple Cubic Carbon Phase C21-sc: A Promising Superhard Carbon Conductor
Chaoyu He, Lijun Meng, Chao Tang +1
Traditionally, all superhard carbon phases including diamond are electric insulators and all conductive carbon phases including graphite are mechanically soft. Based on first-princ…
Two dimensional topological insulators with tunable band gaps: HgTe and HgSe monolayers
Jin Li, Chaoyu He, Lijun Meng +7
Employing ab initio electronic calculations, we propose a new type of two-dimensional (2D) topological insulator (TI), monolayer (ML) low buckled (LB) mercury telluride (HgTe) and…
