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…
14N Hyperfine and nuclear interactions of axial and basal NV centers in 4H-SiC: A high frequency (94 GHz) ENDOR study
F. F. Murzakhanov, M. A. Sadovnikova, G. V. Mamin +6
The nitrogen-vacancy (NV) centers (NCVSi) - in 4H silicon carbide (SiC) constitute an ensemble of spin S = 1 solid state qubits interacting with the surrounding 14N and 29Si nuclei…
Room Temperature Microsecond Coherence of Silicon Dangling Bonds
J. Möser, H. Popli, T. H. Tennahewa +8
Paramagnetic point defects in silicon provide qubits that could open up pathways towards silicon-technology based, low-cost, room-temperature (RT) quantum sensing. The silicon dang…
DFT-Assisted Investigation of the Electric Field and Charge Density Distribution of Pristine and Defective 2D WSe by Differential Phase Contrast Imaging
Maja Groll, Julius Bürger, Ioannis Caltzidis +4
Most properties of solid materials are defined by their internal electric field and charge density distributions which so far are difficult to measure with high spatial resolution.…
