Symmetry-Protected Phonon Topology and Low Lattice Thermal Conductivity in Square-Octagonal Chalcogenides
Nair Surabhi Suresh, Mondal Chiranjith, Alam Aftab +1
Unconventional lattice geometries provide an effective platform for realizing symmetry-protected topological phonon states that can strongly influence lattice heat transport. In th…
Lead-free antiperovskite derivatives BaMA (M = P, As, Sb, Bi; A = Cl, Br, I): Next-gen materials for optoelectronics
Surajit Adhikari, Aftab Alam, Priya Johari
Antiperovskite derivatives have recently emerged as promising lead-free alternatives to halide perovskites for optoelectronic applications. Here, using a comprehensive first-princi…
Carrier Selectivity and Passivation at the Group V elemental 2D Material--Si Interface of a PV Device
Gurudayal Behera, K. R. Balasubramaniam, Aftab Alam
This study investigates the interfacial characteristics relevant to photovoltaic (PV) devices of the Group--V elemental 2D layers with Si. The surface passivation and carrier selec…
Ternary Alkali Metal Copper Chalcogenides ACuX (A= Na, K and X= S, Se, Te): Promising Candidate for Solar Harvesting Applications
Gurudayal Behera, Surabhi Suresh Nair, Nirpendra Singh +2
We report a comprehensive first-principles study of the relative stability of the various possible crystal structures, and the electronic and optical properties of ternary alkali m…
