These are the hot electron photoluminescence (HEPL), and mobility mapping techniques which involve the measurements of PL in synchronization with applied voltage pulse, high field I-V and Hall mobility. In the presence of electric field the carriers are heated, and the high energy-tail of the PL, which is described by Maxwell-Boltzmann distribution, can be used to obtain the temperature of the non-equilibrium carriers. The second technique called mobility mapping is used to verify the temperature of the non-equilibrium carriers.eninfo:eu-repo/semantics/closedAccessGaAsAlGaAs2DEGElectron temperatureArticle3815-63788WOS:000338487000007Q4
