Abstract
Electrically heated metal films have long been used as generators of heat pulses. It is well known, that their phonon-frequency spectrum is that of a black-body radiator [1]. If the phonon source is restricted to two dimensions, however, deviations from this behavior can be expected [2]. This situation is realized with the two-dimensional electron gas (2 DEG) in a MOS device [3].
