Amado, M. ; Lima, R. P. A. ; Gonzalez-Santander, C. ; Domínguez-Adame Acosta, Francisco | American Physical Society | 2007-08We theoretically study donor-bound electron states in two-dimensional quantum rings of finite width. A strong magnetic field is applied perpendicular to the plane of the quantum ring. The resulting electronic states are obtained within the effec[...]texto impreso
We consider the electronic transport through a Rashba quantum dot coupled to ferromagnetic leads. We show that the interference of localized electron states with resonant electron states leads to the appearance of the Fano-Rashba effect. This ef[...]texto impreso
Amado, M. ; Malyshev, Andrey ; Sedrakyan, A. ; Domínguez-Adame Acosta, Francisco | American Physical Society | 2011-08-03We calculate numerically the localization length critical index within the Chalker-Coddington model of the plateau-plateau transitions in the quantum Hall effect. We report a finite-size scaling analysis using both the traditional power-law corr[...]texto impreso
Clericò, Vito ; Delgado Notario, J. A. ; Saiz Bretín, Marta ; Malyshev, Andrey ; Meziani, Y. M. ; Hidalgo Alcalde, Pedro ; Méndez Martín, Bianchi ; Amado, M. ; Domínguez Adame Acosta, Francisco ; Díaz Fernández, Enrique | Nature Publishing Group | 2019-09-19We report on a novel implementation of the cryo-etching method, which enabled us to fabricate low-roughness hBN-encapsulated graphene nanoconstrictions with unprecedented control of the structure edges; the typical edge roughness is on the order[...]
