High Density, Localized Quantum Emitters in Strained 2D Semiconductors
Gwangwoo Kim, Hyong Min Kim, Pawan Kumar +14
Two-dimensional chalcogenide semiconductors have recently emerged as a host material for quantum emitters of single photons. While several reports on defect and strain-induced sing…
Direct Opto-Electronic Imaging of 2D Semiconductor - 3D Metal Buried Interfaces
Kiyoung Jo, Pawan Kumar, Joseph Orr +10
The semiconductor-metal junction is one of the most critical factors for high performance electronic devices. In two-dimensional (2D) semiconductor devices, minimizing the voltage…
Cathodoluminescence as an Effective Probe of Carrier Transport and Deep Level Defects in Droop-Mitigating InGaN/GaN Quantum Well Heterostructures
Zhibo Zhao, Akshay Singh, Jordan Chesin +7
Commercial InGaN/GaN light emitting diode heterostructures continue to suffer from efficiency droop at high current densities. Droop mitigation strategies target Auger recombinatio…
Control and Characterization of Individual Grains and Grain Boundaries in Graphene Grown by Chemical Vapor Deposition
Qingkai Yu, Luis A. Jauregui, Wei Wu +14
The strong interest in graphene has motivated the scalable production of high quality graphene and graphene devices. Since large-scale graphene films synthesized to date are typica…
Hartree simulations of coupled quantum Hall edge states in corner-overgrown heterostructures
Lucia Steinke, Patrick Cantwell, Eric Stach +5
The electronic states in a corner-overgrown bent GaAs/AlGaAs quantum well heterostructure are studied with numerical Hartree simulations. Transmission electron microscope pictures…
