TLDR
A short review on impact avalanche transit time (IMPATT) sources for the generation of terahertz (THz) waves has been presented in this paper, where the noise outputs of the sources at different electromagnetic spectrum have been discussed.Abstract:
A short review on avalanche transit time devices has been presented in this chapter. From its first proposal till the state of the art, impact avalanche transit time (IMPATT) sources for the generation of terahertz (THz) waves have been briefly described. The noise outputs of the sources at different electromagnetic spectrum have been discussed. The details of deferent device structures, potential materials, popular simulation techniques, etc. are also appended in this chapter.read more
