Phonon-assisted photoluminescence of bilayer MoS from first principles
Gyanu P. Kafle, Zhen-Fei Liu
In indirect band gap materials, phonon-assisted processes are key mechanisms for photoluminescence (PL). Using a first-principles many-body approach, we systematically investigate…

Electronic, vibrational, and electron-phonon coupling properties in SnSe and SnS under pressure
Gyanu Prasad Kafle, Christoph Heil, Hari Paudyal +1
The tin-selenide and tin-sulfide classes of materials undergo multiple structural transitions under high pressure leading to periodic lattice distortions, superconductivity, and to…
