Optical and electrical manipulation of single ion spins in semiconductors

摘要

Single ion spins in semiconductors with sizable spin-orbit interaction can be optically or electrically manipulated. The highly extended anisotropic wave function of the hole bound to each magnetic ion is susceptible to external non-magnetic control fields. The spin-orbit coupling between the orbital and spin character of the hole permits indirect manipulation and readout of the ionic spin state. The spin-spin interaction between the magnetic ions is electrically or structurally controllable.
