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 $…
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…
: A new potential two dimensional metal-free photocatalyst for overall water splitting
Sreejani Karmakar, Souren Adhikary, Sudipta Dutta
In this work, using a hybrid density functional theory (DFT) based calculation, we propose a new two-dimensional (2D) B-C-N material, , with the promising prospe…
