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…
Tailoring topological states of core-shell nanoparticles
Carolina Martínez-Strasser, Yuriko Baba, Álvaro Díaz-Fernández +1
In this work we investigate novel spherical core-shell nanoparticles with band inversion. The core and the embedding medium are normal semiconductors while the shell material is as…
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…
Understanding the UV luminescence of zinc germanate: The role of native defects
Jaime Dolado, Ruth Martínez-Casado, Pedro Hidalgo +6
Achieving efficient and stable ultraviolet emission is a challenging goal in optoelectronic devices. Herein, we investigate the UV luminescence of zinc germanate Zn2GeO4 microwires…
Excitons, trions and Rydberg states in monolayer MoS2 revealed by low temperature photocurrent spectroscopy
Daniel Vaquero, Vito Clericò, Juan Salvador-Sánchez +6
We investigate excitonic transitions in a h-BN encapsulated monolayer phototransistor by photocurrent spectroscopy at cryogenic temperature (T = 5 K). The spectra…
Nanoelectronic devices based on twisted graphene nanoribbons
Marta Saiz-Bretín, Andrey V. Malyshev, Francisco Domínguez-Adame
We argue that twisted graphene nanoribbons subjected to a transverse electric field can operate as a variety of nanoelectronic devices, such as tunable tunnel diodes with current-v…
Spin-polarized electric current in silicene nanoribbons induced by atomic adsorption
C. Núñez, P. A. Orellana, L. Rosales +2
We investigate the nonequilibrium transport properties of a silicene armchair nanoribbon with a random distribution of adsorbed atoms in apex positions. A ferromagnetic insulator g…
Intraband exciton relaxation in a biased lattice with long-range correlated disorder
E. Díaz, F. Domínguez-Adame
We study numerically the intraband exciton relaxation in a one-dimensional lattice with scale-free disorder, in the presence of a linear bias. Exciton transport is considered as in…
