Abstract :
High-resolution photon emission spectrometry has been employed to study impact ionization and photon generation dynamics in deep sub-micron MOSFETs. Physical impact ionization - an indirect band-gap recombination model, which is in good agreement with the broadband spectrum properties, has been developed. The abrupt change in the photon emission spectrum profile at 1.8 eV has been attributed to energy-momentum conservation requirements during impact ionization. The abrupt changes in photon intensity with respect to photon energy need to be accounted for in the electron population and electron mean free path derivation, using photoemission methods.
