Pauli blockade in a few-hole PMOS double quantum dot limited by spin-orbit interaction
Résumé
We report on the hole compact double quantum dots fabricated using a conventional CMOS technology. We provide the evidence of Pauli spin blockade in the few hole regime that is relevant to spin qubit implementations. A current dip is observed around zero magnetic field, in agreement with the expected behavior for the case of strong spin-orbit. We deduce an intradot spin relaxation rate approximate to 120 kHz for the first holes, an important step towards a robust hole spin-orbit qubit. Published by AIP Publishing.
