Channels of electron-electron interactions in highly doped heterojunction
Аннотация:
Electron-electron interactions in a single highly doped heterojunction are considered, taking into account both intra- and intersubband transitions. Expressions are derived for the time of electron-electron interaction, matrix elements of the full screening potential and dynamic dielectric function in a 2D electron system with the fine structure of the energy spectrum, and for the electron density spatial distribution. The theoretical dependences τ th ee (T, ns) provide a good description of the experimental times of Landau levels collisional broadening τ exp q (T, ns).
