Introduction of Multi-particle Büttiker Probes -- Bridging the Gap between Drift Diffusion and Quantum Transport
Kuang-Chung Wang, Roberto Grassi, Yuanchen Chu +6
State-of-the-art industrial semiconductor device modeling is based on highly efficient Drift-Diffusion (DD) models that include some quantum corrections for nanodevices. In contras…
Spatially controlled electrostatic doping in graphene p-i-n junction for hybrid silicon photodiode
Tiantian Li, Dun Mao, Nick Petrone +9
Sufficiently large depletion region for photocarrier generation and separation is a key factor for two-dimensional material optoelectronic devices, but few device configurations ha…
Large-scale defects hidden inside a topological insulator grown onto a 2D substrate
Danielle Reifsnyder Hickey, Ryan J. Wu, Joon Sue Lee +7
Topological insulator (TI) materials are exciting candidates for integration into next-generation memory and logic devices because of their potential for efficient, low-energy-cons…
Electrical control of inter-layer excitons in van der Waals heterostructures
A. Chaves, J. G. Azadani, V. Ongun Özçelik +2
We investigate excitons in stacked transition metal dichalcogenide (TMDC) layers under perpendicularly applied electric field, herein MoSe/WSe van der Waals heterostructure…
Mid-infrared Electro-Optic Modulation in Few-layer Black Phosphorus
Ruoming Peng, Kaveh Khaliji, Nathan Youngblood +3
Black phosphorus stands out from the family of two-dimensional materials as a semiconductor with a direct, layer-dependent bandgap in energy corresponding to the spectral range fro…
Enhanced interlayer neutral excitons and trions in trilayer van der Waals heterostructures
Chanyeol Choi, Jiahui Huang, Hung-Chieh Cheng +11
Vertically stacked van der Waals heterostructures constitute a promising platform for providing tailored band alignment with enhanced excitonic systems. Here we report observations…
