Anéis quânticos: efeitos topológicos e de campo elétrico
| Postado em: 01 jan. 1999Quantum rings can be viewed as a class of nanostructures which also presents quantum confinement effects leading to significant changes on optical and electronic properties. In particular, the electronic energy spectrum ... -
Dinâmica de spins em nanoestruturas metálicas
| Postado em: 01 mar. 2011In the present work, we investigate the spin pumping mechanism. In 2002, Tserkovnyak et al. proposed that a precessing magnetization of a magnetic unit coupled to a non-magnetic metal can transfer angular momentum to the ... -
Estudos do transporte em nanoestruturas moleculares quasi unidimensionais a partir de experimentos e modelos teóricos
This thesis comprises detailed experimental and theoretical investigations of the transport properties of one-dimensional nanostructures. Most of the work is dedicated to the exploration of the fascinating effects occurring ... -
