Samenvatting

We analyse the electroluminescence measurements performed on a STM-tipImduced quantum dot in a GaAs layer. Positions of electroluminescence peaks, attributed to the electron-hole recombination in the quantum dot, are very sensitive to the electron tunnelling current even in the case when the current is weak and the effect of the electron charge on the electrostatic potential profile in the structure is negligible. We find, in agreement with experiment, that increasing voltage on the STM-tip results in a red shift of thel electroluminescence peaks, while the peak positions as a function of the electron tunnelling current reveal a blue shift.
