What is PED?
Pulsed Electron Deposition (PED) is a process in which a pulsed (80-100 ns) high power electron beam (~1000 A, 15 kV) penetrates approximately 1 μm into the target resulting in a rapid evaporation of target material. The non-equilibrium heating of the target facilitates stoichiometric ablation of the target material. Under optimum conditions, the target stoichiometry is preserved in the deposited films. All solid state materials – metals, semiconductors and insulators, including those transparent to laser wavelengths in PLD – can be deposited as thin films with PED. By combining PLD and PED, the range of complex materials that can be prepared as thin films can be greatly enhanced.
