Popis:	We analyze the scattering processes of high‐energy (approximately 0.3 eV) electrons impinging at normal incidence on a zero‐temperature two‐dimensional electron gas (2DEG), and derive an expression for the scattering probability. We proceed in calculating the total scattering rate and energy loss of the hot electrons as a function of their energy of incidence. These results are then compared with those of the recent experiments performed on a hot‐electron transistor with a 2DEG base. Our calculated base transfer ratio is in good agreement with the measured value.
