Noise phenomena in semiconductor transport

Different aspects of fluctuation phenomena in semiconductors are recieved. After a brief recall of the basic theoretical properties. the main numerical technique to obtain noise spectra are described. The main attention is drawn to the extraction of microscopic physical information from noise properties. To this end, several cases of interest are described, namely: relation between noise and characteristic times of the system. decomposition of noise spectra, noise properties in devices, discussion of the concept of noise temperature and noise in ballistic systems.
