Abstract :
An entanglement-preserving photodetector converts photon polarisation to electron spin. Up and down spin must respond equally to oppositely polarised photons, creating a requirement for degenerate spin energies. ge≃0, for electrons. The authors present a plot of ge factor against lattice constant, analogous to bandgap against lattice constant, that can be used for g factor engineering of III-V alloys and quantum wells
