Transporte electrónico en ratchets cuánticos
(2006)
"Actualmente, el problema de la miniaturización progresiva de los dispositivos electrónicos ha conducido a la elaboración de sofisticadas técnicas litográficas y de crecimiento cristalino. Gracias a estas técnica es que ...
Enhanced tunneling through nonstationary barriers
(2007-11)
"Quantum tunneling through a nonstationary barrier is studied analytically and by a direct numerical solution of Schrödinger equation. Both methods are in agreement and say that the main features of the phenomenon can be ...
Two-dimensional tunneling in a SQUID
(2010-11)
"Traditionally quantum tunneling in a superconducting quantum interference device (SQUID) is studied on the basis of a classical trajectory in imaginary time under a two-dimensional potential barrier. The trajectory connects ...
Simulating unusual phenomena in low dimensional systems
(2011-12)
"This thesis deals with physics phenomena in low dimensional systems, i.e., systems that range between few atoms and the bulk. The work deals with well studied (in this sense, classical) phenomena such as quantum tunneling ...
Atomic surface segregation and structural characterization of PdPt bimetallic nanoparticles
(MDPI, 2018)
"Bimetallic nanoparticles are of interest since they lead to many interesting electrical, chemical, catalytic, and optical properties. They are particularly important in the field of catalysis since they show superior ...
