Abstract
Persistent lateral infra-red photoconductivity has been observed and investigated in InAs/GaAs layers with quantum dots (QD) in the temperature range 4.2<T<300 K. The relaxation of photoconductivity was logarithmic in a certain time range after switching off the light, while the rate of the decay of photoconductivity increases strongly when temperature increases.
