M. GUNES1,*
The results of the experimental techniques used in the determination of the power and momentum losses from a 2DEG were presented. 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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
