Impact of vacancies on twisted bilayer graphene quantum point contacts
Pablo Moles, Francisco Domínguez-Adame, Leonor Chico
We carry out an extensive numerical study of low-temperature electronic transport in quantum point contacts based on twisted bilayer graphene. Assuming ballistic electron dynamics,…
Impact of electron-electron interactions on the thermoelectric efficiency of graphene quantum point contacts
Irián Sánchez-Ramírez, Yuriko Baba, Leonor Chico +1
Thermoelectric materials open a way to harness dissipated energy and make electronic devices less energy-demanding. Heat-to-electricity conversion requires materials with a strongl…
Topological bands in the PdSe pentagonal monolayer
Sergio Bravo, M. Pacheco, J. D. Correa +1
The electronic structure of monolayer pentagonal palladium diselenide (PdSe2) is analyzed from the topological band theory perspective. Employing first-principles calculations, eff…
Charge-spin interconversion in graphene-based systems from density functional theory
Maedeh Rassekh, Hernán Santos, Andrea Latge +3
We present a methodology to address, from first principles, charge-spin interconversion in two-dimensional materials with spin-orbit coupling. Our study relies on an implementation…
Persistence of symmetry-protected Dirac points at the surface of the topological crystalline insulator SnTe upon impurity doping
Olga Arroyo-Gascón, Yuriko Baba, Jorge I. Cerdá +4
We investigate the effect of a non-magnetic donor impurity located at the surface of the SnTe topological crystalline insulator. In particular, the changes on the surface states du…
Fast response photogating in monolayer MoS2 phototransistors
Daniel Vaquero, Vito Clericò, Juan Salvador-Sánchez +6
Two-dimensional transition metal dichalcogenide (TMD) phototransistors have been object of intensive research during the last years due to their potential for photodetection. Photo…
