It is shown that screening only slightly modifies the predictions of the approximate calculations. © 1998 Academic Press.English2D warm electronsEnergy relaxationPower lossScreeningPhononsPiezoelectricitySemiconducting gallium arsenideSemiconductor quantum wellsTwo dimensional electron gasHeterojunctionsThe static and dynamic screening of power loss of a two-dimensional electron gasArticle10.1006/spmi.1998.0569
