| Research Abstract |
Ultramicrocrystalline Si : H binary compound semiconductor has been prepared by the hydrogen plasma chemical sputtering (HPCS) process. The process was carried out in an rf magnetron sputtering system with pure hydrogen gas. The films were grown through the process such as the chemical reactions between the hydrogen plasma and the Si target, hydrogenated molecules evaporation from the target surface, decomposition of the hydrogenated molecules in the hydrogen plasma, and the deposition onto the surface the substrates. The ultimate small Si : H particles with the average grain size as small as 1nm was obtained by adjusting the sputtering power and choosing the substrate materials. Sb and P doping into the films was achieved by the HPCS process using the doped targets.
High quality II-VI compound semiconductor (ZnS, CdS, CdTe, SrS) films were also obtained by the HPCS. The porycrystalline ZnS films were grown onto the glass substrates at 20^ﾟC and the epitaxial ones were grown onto (100) GaAs at 200^ﾟC. A Mn element doping was realized into the ZnS films, which enable us to fabricate an electroluminescent device.
