Multi-functional Wafer-Scale Van der Waals Heterostructures and Polymorphs
M. Micica, A. Wright, S. Massabeau +19
Van der Waals heterostructures have promised the realisation of artificial materials with multiple physical phenomena such as giant optical nonlinearities, spin-to-charge interconv…
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…
Atomic Layer-controlled Nonlinear Terahertz Valleytronics in Dirac Semi-metal and Semiconductor PtSe2
Minoosh Hemmat, Sabrine Ayari, Martin Micica +16
Platinum diselenide (PtSe2) is a promising two-dimensional (2D) material for the terahertz (THz) range as, unlike other transition metal dichalcogenides (TMDs), its bandgap can be…
Free carrier absorption in cascade structures due to static scatterers in the in-plane polarization
Camille Ndebeka-Bandou, Francesca Carosella, Robson Ferreira +1
We report on the computation of the free carrier absorption induced by static scatterers in cascade structures when the electromagnetic wave propagates along the growth axis. We fi…
One dimensional massless Dirac bands in semiconductor superlattices
Francesca Carosella, Andreas Wacker, Robson Ferreira +1
Semiconductor superlattices may display dispersions that are degenerate either at the zone center or zone boundary. We show that they are linear upon the wave-vector in the vicinit…
Relevance of intra- and inter-subband scattering on the absorption in heterostructures
Camille NDebeka-Bandou, Francesca Carosella, Robson Ferreira +2
We analyze the absorption lineshape for inter-subband transitions in disordered quasi 2D heterostructures by an exact calculation. The intra-subband scatterings control the central…
