The optical absorption in indirect semiconductor to semimetal PtSe2 arises from direct transitions
Marin Tharrault, Sabrine Ayari, Mehdi Arfaoui +12
is a van der Waals material transitioning from an indirect bandgap semiconductor to a semimetal with increasing thickness. Its absorption threshold has been conjectur…
Electroluminescence and Energy Transfer Mediated by Hyperbolic Polaritons
L. Abou-Hamdan, A. Schmitt, R. Bretel +26
Under high electrical current, some materials can emit electromagnetic radiation beyond incandescence. This phenomenon, referred to as electroluminescence, leads to the efficient e…
Raman spectroscopy of monolayer to bulk PtSe2 exfoliated crystals
Marin Tharrault, Eva Desgué, Dominique Carisetti +4
Raman spectroscopy is widely used to assess the quality of 2D materials thin films. This report focuses on , a noble transition metal dichalcogenide which has the rema…
Electroluminescence of the graphene 2D semi-metal
A. Schmitt, L. Abou-Hamdan, M. Tharrault +18
Electroluminescence, a non-thermal radiative process, is ubiquitous in semi-conductors and insulators but fundamentally precluded in metals. We show here that this restriction can…
