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…
Exact Bloch oscillations in optical waveguide arrays with arbitrary long-range coupling
R. Arjona, E. Diaz, F. Dominguez-Adame
We find the exact Bloch oscillations in zigzag arrays of curved optical waveguides under the influence of arbitrary long-range coupling. The curvature induces a linear transverse p…
Contact effects in spin transport along double-helical molecules
Ai-Min Guo, E. Díaz, C. Gaul +4
We report on spin transport along double-helical molecular systems by considering various contact configurations and asymmetries between the two helical strands in the regime of co…
Super Bloch oscillations with modulated interaction
Elena Díaz, Alberto García Mena, Kunihiko Asakura +1
We study super Bloch oscillations of ultracold atoms in a shaken lattice potential, subjected to a harmonically modulated mean-field interaction. Usually, any interaction leads to…
Super Bloch oscillations in the Peyrard-Bishop-Holstein model
C. Herrero-Gómez, E. Díaz, F. Domínguez-Adame
Recently, polarons in the Peyrard-Bishop-Holstein model under DC electric fields were established to perform Bloch oscillations, provided the charge-lattice coupling is not large.…
