Surface-exciton enhanced SHG response in few-layer 2H-TMDC
H. Hübschmann, G. Berth, M. Groll +6
We explore the nonlinear optical properties of few-layer MoS2 by means of polarization and laser-power-dependent measurements as well as ab initio techniques. While for even layer…

Second harmonic study of thermally oxidized mono- and few-layer 2H-MoS2
Katharina Burgholzer, Henry Volker Hübschmann, Gerhard Berth +5
A comprehensive study of second harmonic generation on thermally oxidized MoS2 flakes with thickness ranging from monolayer up to seven layers is presented. Observing the fundament…

Topological Defects in Semiconducting Carbon Nanotubes as Triplet Exciton Traps and Single-Photon Emitters
Timur Biktagirov, Uwe Gerstmann, Wolf Gero Schmidt
We investigate the role of topological defects in exciton behavior in (6,5) semiconducting single-walled carbon nanotubes using density functional theory. Our study identifies the…
