Key properties in PbSrSe thin films and PbSe/PbSrSe quantum wells for mid-infrared optoelectronic applications

We review our recent investigations on PbSrSe thin film and PbSe/PbSrSe quantum well structures grown by MBE techniques for MIR optoelectronic applications. The band structures, effective mass, phonon behaviour, refractive indices etc, have been investigated by IR absorption and PL spectroscopies under different compositions, temperatures and structures, and combined with some model calculations.
