Strain engineering in Ge/GeSi spin qubits heterostructures

Lorenzo Mauro, Esteban A. Rodríguez-Mena, Biel Martinez +1

The heavy-holes in Ge/GeSi heterostructures show highly anisotropic gyromagnetic response with in-plane $g$-factors $g_{x,y}^{\ast }\lesssim 0.3$ and out-of-plane $g$-factor $g_z^*\gtrsi…
