Strain-Modulated Interlayer Charge and Energy Transfers in MoS2/WS2 Heterobilayer
Joon-Seok Kim, Nikhilesh Maity, Myungsoo Kim +5
Excitonic properties in 2D heterobilayers are closely governed by charge transfer (CT) and excitonic energy transfer (ET) at van der Waals interfaces. Various means have been emplo…
Stacking Order Driven Optical Properties and Carrier Dynamics in ReS2
Yongjian Zhou, Nikhilesh Maity, Amritesh Rai +8
Two distinct stacking orders in ReS2 are identified without ambiguity and their influence on vibrational, optical properties and carrier dynamics are investigated. With atomic reso…
Pressure-Induced Topological Phase Transitions in CdGeSb and CdSnSb
Rinkle Juneja, Ravindra Shinde, Abhishek K. Singh
Topological quantum phase transitions (TQPTs) in a material induced by external perturbations are often characterized by band touching points in the Brillouin zone. The low-energy…
Topological semimetals with nodal-rings and nexus fermions
Mighfar Imam, Ranjan Kumar Barik, Rinkle Juneja +2
Based on the first-principles study, we report a new set of topological semimetals (TiS, TiSe, TiTe, HfS, HfSe, HfTe and ZrS) which show the co-existence of a nodal-ring and triply…
