Exciton fine structure in twisted transition metal dichalcogenide heterostructures
Sudipta Kundu, Tomer Amit, H. R. Krishnamurthy +2
Moiré superlattices of transition metal dichalcogenide (TMD) heterostructures give rise to rich excitonic phenomena associated with the interlayer twist angle and induced changes i…
Tuning exciton complexes in twisted bilayer WSe2 at intermediate misorientation
Rahul Debnath, Shaili Sett, Sudipta Kundu +5
Twist angle modifies the band alignment, screening, and interlayer (IL) coupling in twisted bilayers (tBLs) of transition metal dichalcogenides. Intermediate misorientation (twist…
Atomic relaxation and flat bands in strain-engineered transition metal dichalcogenide bilayer moiré systems
Sudipta Kundu, Indrajit Maity, Robin Bajaj +2
Strain-induced lattice mismatch leads to moiré patterns in homobilayer transition metal dichalcogenides (TMDs). We investigate the structural and electronic properties of such stra…
Moiré induced topology and flat bands in twisted bilayer WSe: A first-principles study
Sudipta Kundu, Mit H. Naik, H. R. Krishnamurthy +1
We study the influence of strong spin-orbit interaction on the formation of flat bands in relaxed twisted bilayer WSe. Flat bands, well separated in energy, emerge at the band…
Population Analysis with Wannier Orbitals
Sudipta Kundu, Satadeep Bhattacharjee, Seung-Cheol Lee +1
We formulate Wannier orbital overlap population and Wannier orbital Hamilton population to describe the contribution of different orbitals to electron distribution and their intera…
Native Point Defects in Mono-- and Bi--layer Phosphorene
Sudipta Kundu, Mit H. Naik, Manish Jain
We study the stability and electronic properties of intrinsic point defects, vacancy and self-interstitial, in mono- and bi-layer phosphorene. We calculate the formation energies,…
Origin and Evolution of Ultraflatbands in Twisted Bilayer Transition Metal Dichalcogenides: Realization of Triangular Quantum Dot Array
Mit H. Naik, Sudipta Kundu, Indrajit Maity +1
Using a multiscale computational approach, we probe the origin and evolution of ultraflatbands in moiré superlattices of twisted bilayer MoS, a prototypical transition metal di…
Opening of large band gap in metallic carbon nanotubes by mannose functionalized dendrimers: Experiments and theory
K. S. Vasu, Debabrata Pramanik, Sudipta Kundu +5
Despite many theoretical schemes, the direct experimental observation of supramolecular control on band gap opening in single-walled carbon nanotubes (SWNT) is still lacking. We re…
PASTA: Python Algorithms for Searching Transition stAtes
Sudipta Kundu, Satadeep Bhattacharjee, Seung-Cheol Lee +1
Chemical reactions are often associated with an energy barrier along the reaction pathway which hinders the spontaneity of the reaction. Changing the energy barrier along the react…
