Transport properties along the channel of a Hemt
… channel. In this study, the scattering rates for polar optical phonons (POP), acoustic phonons (AP) through deformation potential and impurity scattering are obtained theoretically based on the Fermi's golden rule as a function of position along the channel for an …

Theoretical studies of electron dynamics and relaxation in photoexcited quantum well structures
… and interpreting the results from the various optical experiments performed on QW structures. First, the transfer matrix technique used to calculate the electronic properties of QW structures is described. Next, a general discussion of the electron-phonon interactions important for QW …

Carrier momentum relaxation in highly doped polar semiconductors and semiconductor heterostructures
Highly doped polar semiconductors are essential components of today’s semiconductor industry. Most strikingly, transistors in modern electronic devices are polar semiconductor heterostructures. It is important to thoroughly understand carrier transport in such structures. In doped polar …
