Semiconductor Engineering for High-Speed Devices

Abstract

Phonon scattering is treated only in the long wavelength limit. We have found that such and approximation is invalid in hot electron transport studies due to large momentum transfers involved. We are currently evaluating these rates from ab initio calculation. The results of this calculation are expected to include the effect of intervalley scattering mediated by LO and acoustic phonons more accurately. The analysis is completed, and computer evaluations of the result for several semiconductors are in process. This may change some of our quantitative conclusions.
