Symmetry-Selective Shift Current in Polar Multidomain Superlattices
Tomoaki Kameda, Kosuke Nagashio, Katsunori Wakabayashi
Periodic polar multidomain superlattices can act as symmetry-selective elements for shift-current generation. We demonstrate this using a two-dimensional Su-Schrieffer-Heeger model…
Hot-Carrier Distribution Spectroscopy by Transconductance in Two-Dimensional Field-Effect Transistors
Katsunori Wakabayashi
The transconductance of a field-effect transistor (FET) is conventionally read as a proxy for carrier density. We show that it is instead a spectroscopic probe of…
Strain Effects on Electronic Properties of Cobalt-Based Coordination Nanosheets
Kento Nishigomi, Yu Yi, Souren Adhikary +2
We theoretically study the strain effects on the electronic properties of cobalt-based benzenehexathiol (CoBHT) coordination nanosheets using first-principles calculations. Two dis…
Optically induced spin Hall current in monolayer Janus NbSSe: A first-principles study
Souren Adhikary, Tomoaki Kameda, Katsunori Wakabayashi
Monolayer Janus transition-metal dichalcogenides possess Ising- and Rashba-type spin-orbit-couplings (SOC), leading to intriguing spin splitting effects at K and K, and around $…
Optically induced spin Hall current in Janus transition-metal dichalcogenides
Tomoaki Kameda, Katsunori Wakabayashi
Monolayer Janus transition-metal dichalcogenides (TMDCs), such as WSeTe, exhibit Rashba-type spin-orbit coupling (SOC) due to broken out-of-plane mirror symmetry. Here, we theoreti…
