Abstract
Experimental evidence for thermal excitation of plasmons in two-dimensional electron systems is reported. The spectral intensity and temperature dependence of the thermal excitation are calculated by means of Bose-Einstein statistics, and give quantitative agreement with the results of far-infrared emission experiments. It is found that the plasmons may contribute significantly to the specfic heat of the two-dimensional electron system at low electron densities and high temperatures.
