Presents a study that measured photoluminescence (PL) spectra for cadmium telluride (CdTe) epilayers grown by radio frequency magnetron sputtering. Significance of PL spectroscopy; Comparison of the crystalline quality of the CdTe epilayers as a function of film thickness; Observation on the general shape of the PL spectra for the epilayers.

Examines the plasma potential and electron density of a radio frequency (rf)-magnetron discharge used for ion-assisted growth of PbTe epilayers. Application of Langmuir probe diagnostics in the study; Effect of rf potentials at the probe with regard to the measured plasma parameters of the lead compound; Assessment of discharge parameters of the rf potentials.

Examines the emission spectroscopy diagnostics of a magnetron sputter discharge. Features of the sputter deposition apparatus; Method used to improve the light-gathering capability of the apparatus for measurements of intensity versus radio frequency (rf) power and gas pressure; Determination of the rf power.

Epitaxial (111)CdxPb1-xTe//(111)BaF2 films in the rocksalt structure have been made by codeposition from CdTe and PbTe magnetron targets in an rf discharge onto chemipolished substrates at 320 °C. Films were prepared with x values from 0 to 0.47, well past the range of bulk thermodynamic solubility. Raman spectroscopy, Auger spectroscopy, and transmission electron microscopy showed phase segregation had not occurred. The lattice spacing in the growth direction was observed to be insensitive to x. [ABSTRACT FROM AUTHOR]
