Andreev Reflection in the Quantum Hall Regime at an Al/InAs Junction on a Cleaved Edge
Takafumi Akiho, Hiroshi Irie, Yusuke Nakazawa +3
We have fabricated a superconductor/semiconductor (S/Sm) junction composed of Al and InAs using cleaved edge overgrowth. By exploiting the unique geometry with a thin Al/Pt/Al tril…
Andreev reflection of fractional quantum Hall quasiparticles
Masayuki Hashisaka, Thibaut Jonckheere, Takafumi Akiho +4
Electron correlation in a quantum many-body state appears as peculiar scattering behaviour at its boundary, symbolic of which is Andreev reflection at a metal-superconductor interf…
A vertical diatomic artificial molecule in the intermediate coupling regime in a parallel and perpendicular magnetic field
F. Ancilotto, D. G. Austing, M. Barranco +4
We present experimental results for the ground state electrochemical potentials of a few electron semiconductor artificial molecule made by vertically coupling two quantum dots, in…
Ellipsoidal deformation of vertical quantum dots
D. G. Austing, S. Sasaki, S. Tarucha +3
Addition energy spectra at 0 T of circular and ellipsoidally deformed few-electron vertical quantum dots are measured and compared to results of model calculations within spin-dens…
