Abstract

The variation of the magnetoconductance of two quantum dot arrays fabricated on GaAs/AlGaAs with temperature and sample current was used to extract carrier heating values at various magnetic fields. These measurements yielded a power law dependence of the electron temperature with the sample current and we study its variation with magnetic field. The power law exponent for the energy-relaxation time for both the dot arrays stays nearly constant over the entire magnetic field range.
