Transconductance as a Probe of Valley Thermodynamics in Multilayer WSe
Katsunori Wakabayashi, Souren Adhikary, Tomoaki Kameda
Transconductance is a central figure of merit in field-effect transistors, typically governed by charge accumulation and carrier mobility. In multilayer WSe transistors, howeve…
Valley-Landscape Engineering in Bilayer WSe Gate-All-Around Transistors
Katsunori Wakabayashi, Souren Adhikary, Kazuhito Tsukagoshi
The K- valence-band splitting that governs hole transport in few-layer WSe is not a fixed material constant. It is tuned by interlayer stacking, strain, pressure, a…
Dilute Magnetism and Edge-State Engineering in Monolayer SnO
Yuya Fukuta, Souren Adhikary, Kazuhito Tsukagoshi +1
Tin monoxide (SnO) is a p-type oxide semiconductor whose electronic properties can be widely modified via atomic-scale engineering. Using density functional theory, we investigate…
Excitonic circular dichroism in boron-nitrogen clusters decorated graphene
Shneha Biswas, Souren Adhikary, Sudipta Dutta
Within the first principle calculations, we propose a boron and nitrogen cluster incorporated graphene system for efficient valley polarization. The broken spatial inversion symmet…
Circular dichroism in two-dimensional BCN and BCN in absence of intervalley excitonic coupling
Souren Adhikary, Sudipta Dutta
Two-dimensional (2D) noncentrosymmetric systems offer potential opportunities for exploiting the valley degrees of freedom for advanced information processing, owing to non-zero Be…
Valley-polarization and stable triplet exciton formation in 2D lateral heterostrcuture of hBN-kagome and graphene
Souren Adhikary, Sasmita Mohakud, Sudipta Dutta
Broken spatial inversion symmetry in semiconducting materials with time-reversal pair valleys can exhibit valley polarization. Based on first-principles calculations, here we propo…
