A p-type GaAs/AlGaAs multi-quantum-well infrared photodetector(QWIP) was fabricated on a GaAs (111)A substrate by molecular-beam epitaxy using silicon as dopant. The same structure was also grown on a GaAs (100) wafer simultaneously to compare the material and structural properties. It was found tha...
