Defect-induced -magnetism in layered platinum diselenide
Priyanka Manchanda, Pankaj Kumar, Pratibha Dev
Platinum diselenide (PtSe) is a recently-discovered extrinsic magnet, with its magnetism attributed to the presence of Pt-vacancies. The host material to these defects itself…
A new class of intrinsic magnet: two-dimensional yttrium sulphur selenide
Pankaj Kumar, Ivan I. Naumov, Priyanka Manchanda +1
Exploring and controlling magnetism in two-dimensional (2D) layered magnetic crystals, as well as their inclusion in heterogeneous assemblies, provide an unprecedented opportunity…
Thickness-dependence of hydrogen-induced phase transition in MoTe
Priyanka Manchanda, Pankaj Kumar, Pratibha Dev
Two-dimensional transition metal dichalcogenides (TMDs) usually exist in two or more structural phases with different physical properties, and can be repeatedly switched between th…
Quantum materials interfaces: graphene/Bismuth (111) heterostructures
Ivan I. Naumov, Pratibha Dev
Heterostructures involving graphene and bismuth, with their ability to absorb light over a very wide energy range, are of interest for engineering next-generation opto-electronics.…
Fingerprinting quantum emitters in hexagonal boron nitride using strain
Pratibha Dev
Two dimensional van der Waals crystals and their heterostructures provide an exciting alternative to bulk wide bandgap semiconductors as hosts of single photon emitters. Amongst di…
Controlling the Infrared Dielectric Function through Atomic-Scale Heterostructures
Daniel C. Ratchford, Christopher J. Winta, Ioannis Chatzakis +20
Surface phonon polaritons (SPhPs) - the surface-bound electromagnetic modes of a polar material resulting from the coupling of light with optic phonons - offer immense technologica…
