Abstract:

We have measured random telegraph noise in the photoluminescence of individual quantum dots of InGaAs in GaAs. We have observed not only two-level dots but also dots switching among three level in both systems. The experiments show that the switching InGaAs dots behave very similarly to switching InP dots in GaInP. The switching is attributed to defects and we show that the switching can be used as a monitor of the defect.
