Field - Free and Field - Stimulated Electron Emission from Solids
Electron irradiation of solids produces a backemission of secondary electrons (energies between 0 and 50 eV) and re ected primaries (energies between 50 eV and that of the incident beam). For insulators, it is shown that an externally applied positive electric eld penetrating into the solid material, energizes electrons generated by the primary irradiation and enables them to travel back to the...
متن کاملThermally stimulated H emission and diffusion in hydrogenated amorphous silicon
We report first principles ab initio density functional calculations of hydrogen dynamics in hydrogenated amorphous silicon. Thermal motion of the host Si atoms drives H diffusion, as we demonstrate by direct simulation and explain with simple models. Si-Si bond centers and Si ring centers are local energy minima as expected. We also describe a new mechanism for breaking Si-H bonds to release f...
متن کاملThermally Stimulated Currents
Thermally stimulated current-curves in CdS platelets with slit electrodes change their character when the photoelectric gain-factor increases above one. Here the photocurrent remains essentially frozen-in up to temperatures at which marked thermal quenching sets in. A positive space charge region is assumed to be responsible for the frozen-in photocurrent. A reliable TSC-analysis of the trap di...
متن کاملIncreased terahertz emission from thermally treated GaSb
We report on the terahertz (THz) emission from GaSb surfaces with modified surface stochiometry. While very weak emission is observed from virgin GaSb wafers, the emission is significantly increased by a single thermal treatment of the wafers. Optimum emission is observed for 500 °C thermal annealing. The reason for the THz emission is a surface electric field induced by thermal decomposition o...
