Spin Blockade in Capacitively Coupled Quantum Dots
arXiv:cond-mat/0310469 · doi:10.1063/1.1776613
Abstract
We present transport measurements on a lateral double dot produced by combining local anodic oxidation and electron beam lithography. We investigate the tunability of our device and demonstrate, that we can switch between capacitive and tunnel coupling. In the regime of capacitive coupling we observe the phenomenon of spin blockade in a magnetic field and analyze the influence of capacitive interdot coupling on this effect.
