Symmetry-Based Design Rules for Second-Harmonic Generation in Stacked and Twisted MoS2 Bilayers
Sumanti Patra, Caterina Cocchi
Understanding how stacking controls the nonlinear optical response of two-dimensional materials is key to designing van der Waals heterostructures with tailored functionalities. He…

Exciton fine structure in CdSe nanoplatelets using a quasi-2D screened configuration-interaction framework
Sumanti Patra, Gabriel Bester
We compute exciton binding energies and fine-structure splittings in CdSe nanoplatelets with two zincblende geometries and one wurtzite geometry, finding that the wurtzite structur…

The role of stacking on the electronic structure of MoSe2 at small twist angles
Sumanti Patra, Madhurita Das, Priya Mahadevan
We consider two high symmetry stackings AA and AB and examine the changes induced in the electronic structure by considering small angles of rotation of 3.48degrees from both these…
