Abstract

Since a quantum dot has an extremely long spin relaxation time, we must consider two spin selection rules for its transport characteristics. Namely, the total spin of the quantum dot is conserved during internal transitions, and it should change by ±1/2 during a single-electron tunneling transition. We find that these selection rules are strictly obeyed in transport through a few-electron vertical quantum dot, and that related non-equilibrium transport can break the single-electron tunneling scheme.
