Popis: There is still a great deal more to be learned about the details of the electron-phonon interaction in 2DEG systems. Some of this may emerge from more experimental and theoretical work on electrical transport particularly in high magnetic fields and thermoelectric power seems likely to be a worthwhile area of investigation for some time to come. It is also clear that phonon work by a variety of techniques has very considerable potential in this area and in principle can provide detailed information about the interaction with specific phonon modes which is not possible to obtain in any other way. The suggestion that cyclotron phonon emission from a hot 2DEG might be a useful tuneable source of 'monochromatic' phonons has still to be explored experimentally.
