Description
Intersubband transitions in In0.52Ga0.48As/In0.52Al0.48As multiple quantum wells (MQWs) were investigated as a function of 1 MeV proton irradiation dose and thermal annealing temperature. It is observed that proton doses as high as 1x1014 cm-2 do not have a measurable effect on the intensity or the peak position energy of the intersubband transitions. While a dose of 1x1014 cm-2 has shown a detrimental effect on the intersubband transitions in the GaAs/AlGaAs MQWs, the intersubband transitions in InGaAs/InAlAs MQWs withstood proton doses as high as 1x1015 cm-2 and completely depleted after irradiation with a dose of 3x1015 cm-2. Furnace thermal annealing of the heavily irradiated samples shows that the depleted intersubband transitions in InGaAs/InAlAs MQW samples were almost completely recovered
