Abstract
A high resolution electron spectrometer has been used to demonstrate experimentally that both thermal (T varying from ~300-700 K) and photo (λ ~350nm) stimulation can enhance the field-induced hot-electron emission from a metal-insulator-metal (MIM) microstructure. A detailed analysis of electron energy spectra has provided relationships between temperature and such emission parameters as current, spectral half-width and spectral shift. These studies have also provided valuable information about electron transport in the MIM structure and the electron energy distribution in the metal-insulator interface in immediate proximity to the vacuum.
