g-factor anisotropy in nanowire-based InAs quantum dots

Abstract

The determination and control of the electron $g$-factor in semiconductor\nquantum dots (QDs) are fundamental prerequisites in modern concepts of\nspintronics and spin-based quantum computation. We study the dependence of the\n$g$-factor on the orientation of an external magnetic field in quantum dots\n(QDs) formed between two metallic contacts on stacking fault free InAs\nnanowires. We extract the $g$-factor from the splitting of Kondo resonances and\nfind that it varies continuously in the range between $|g^*| = 5$ and 15.\n
