Spin Transport Properties of a Quantum Dot

Abstract

During the last decade, spin phenomena in the transport properties of low-dimensional quantum systems have become a subject of increasing interest [1, 2]. Several fundamental effects have been found when controlling transport of electrons one by one in quantum dots. For instance, parity effects in the Coulomb blockade of quantum dots with very small numbers of electrons have been detected experimentally [3]. In addition, the spin blockade effect, especially in the non-linear current-voltage characteristic of one-dimensional (1D) quantum dots has been predicted [4].
