Monte-Carlo Simulation of High-Field Electron Transport in Alternating- Current Thin-Film Electroluminescent Devices
Abstract
We present an ensemble Monte Carlo simulation of electron transport in bulk ZnS at high electric fields. Scattering mechanisms associated with polar optical phonons, acoustic phonons (through deformation potential coupling), intervalley scattering, and impurities (neutral and ionized) are included in a nonparabolic multi-valley model. The simulated results show that energetic electrons are available for impact excitation at fields exceeding 1 MV/cm, and that transient effects are negligible in explaining measured efficiencies in ACTFEL devices....
