Sierra, Miguel A. ; Sánchez, David ; Gutiérrez, Rafael ; Cuniberti, Gianaurelio ; Domínguez-Adame Acosta, Francisco ; Díaz García, Elena | MDPI | 2020-01The helical distribution of the electronic density in chiral molecules, such as DNA and bacteriorhodopsin, has been suggested to induce a spin-orbit coupling interaction that may lead to the so-called chirality-induced spin selectivity (CISS) ef[...]texto impreso
Motivated by the recent experimental demonstration of spin selective effects in monolayers of double-stranded DNA oligomers, our work presents a minimal model to describe electron transmission through helical fields. Our model highlight that the[...]texto impreso
Díaz García, Elena ; Domínguez-Adame Acosta, Francisco ; Gutiérrez, Rafael ; Cuniberti, Gianaurelio ; Mujica, Vladimiro | Amer Chemical Soc | 2018We use a nonlinear master equation formalism to account for thermal and disorder effects on spin-dependent electron transport in helical organic molecules coupled to two ideal leads. The inclusion of these two effects has important consequences [...]texto impreso
Dolado Fernández, Jaime ; Martínez Casado, Ruth ; Hidalgo Alcalde, Pedro ; Gutiérrez, Rafael ; Dianat, Arezoo ; Cuniberti, Gianaurelio ; Domínguez-Adame Acosta, Francisco ; Díaz García, Elena ; Méndez Martín, Bianchi | Pergamon-Elsevier Science Ltd | 2020-09-01Achieving efficient and stable ultraviolet emission is a challenging goal in optoelectronic devices. Herein, we investigate the UV luminescence of zinc germanate Zn_2GeO_4 microwires by means of photoluminescence measurements as a function of te[...]
