We succeeded in planing the surfaces of diamond films, synthesized by microwave plasma CVD, by using penning discharge micro-sputtering. In this paper we observed the etched diamond film surface by SEM and measured the etching rates under the conditions of Ar and (Ar+O2) gas sputterings with Au and Ti targets. Thus the planed surfaces of diamond films were obtained and new materials were deposited on the films with choosing adequate targets and gases. These experimental results suggest some new application.
The influence of Mn addition on the activation energy of dipoles of BaTiO3 was investigated using the thermal sampling method, which is thermally stimulated current (TSC) measurement technique. The results indicate that the activation energies of dipoles of Mn free and Mn doped (0.1mol%) specimens were 0.2eV and 0.4eV, respectively.
