Gate-tunable Electronic Transport in p-type GaSb Quantum Wells
Matija Karalic, Christopher Mittag, Michael Hug +6
We investigate two-dimensional hole transport in GaSb quantum wells at cryogenic temperatures using gate-tunable devices. Measurements probing the valence band structure of GaSb un…
π junction transition in InAs self-assembled quantum dot coupled with SQUID
S. Kim, R. Ishiguro, M. Kamio +5
We report the transport measurements on the InAs self-assembled quantum dots (SAQDs) which have a unique structural zero-dimensionality, coupled to a superconducting quantum interf…
High Kondo temperature (TK ~ 80 K) in self-assembled InAs quantum dots laterally coupled to nanogap electrodes
K. Shibata, K. Hirakawa
We have fabricated single electron tunneling structures by forming nanogap metallic electrodes directly upon single self-assembled InAs quantum dots (QDs). The fabricated samples e…
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…
Lateral electron tunneling through single self-assembled InAs quantum dots coupled to superconducting nanogap electrodes
K. Shibata, C. Buizert, A. Oiwa +2
We have fabricated superconductor-quantum dot-superconductor (SC-QD-SC) junctions by using SC aluminum electrodes with narrow gaps laterally contacting a single self-assembled InAs…
Kondo Universal Scaling for a Quantum Dot Coupled to Superconducting Leads
Christo Buizert, Akira Oiwa, Kenji Shibata +2
We study competition between the Kondo effect and superconductivity in a single self-assembled InAs quantum dot contacted with Al lateral electrodes. Due to Kondo enhancement of An…
