Spin-Related Current Suppression in a Semiconductor-Quantum-Dot Spin-Diode Structure
K. Hamaya, M. Kitabatake, K. Shibata +6
We experimentally study the transport features of electrons in a spin-diode structure consisting of a single semiconductor quantum dot (QD) weakly coupled to one nonmagnetic (NM) a…

Kondo effect in a semiconductor quantum dot coupled to ferromagnetic electrodes
K. Hamaya, M. Kitabatake, K. Shibata +7
Using a laterally-fabricated quantum-dot (QD) spin-valve device, we experimentally study the Kondo effect in the electron transport through a semiconductor QD with an odd number of…

Electric-field control of tunneling magnetoresistance effect in a Ni/InAs/Ni quantum-dot spin valve
K. Hamaya, M. Kitabatake, K. Shibata +6
We demonstrate an electric-field control of tunneling magnetoresistance (TMR) effect in a semiconductor quantum-dot (QD) spin-valve device. By using ferromagnetic Ni nano-gap elect…
