Spin relaxation in InSb and InAs by 1- and 2-colour spectroscopy with free electron and solid state lasers


We report time-resolved measurement of spin lifetimes in both bulk and quantum well narrow gap semiconductors (NGSs) at 300K. We have used both free electron and solid state laser sources from 3 to 7 /spl mu/m and quarter wave plates to produce circularly polarised pump and probe beams. We previously demonstrated that spin flip (Elliott-Yafet, EY… (More)
