The use of spectroscopy methods for structural analysis of CVD diamond films, polycrystalline and single-crystal diamonds

For the work results correct interpretation, it is important to study initial materials that scientists have deal with. Currently, there are a large number of different diamond substrates. Comparison among themselves allows you determine which material dealing In this work, methods infrared (IR) spectrometry, Raman spectroscopy and spectrophotometry used four types materials: polycrystalline CVD-films; natural single-crystal diamonds; synthetic HPHT-diamonds (such as DSPC – polycrystal by GOST 9206-80); CVD-diamonds CDM manufactured E6. was shown measure effect heat treatment on changes in structure, even if such highly advanced diamonds. Heat affects perfection crystal structure reducing stresses defects due graphitization process. The IR spectrometry method effective for determining shape amount nitrogen inclusions structure. To CVD-films, turned out be most effective, because made possible small draw conclusions about quality films. investigation diamonds demonstrated that, despite their coarse-crystalline crystallites consist defective phase; addition, DSPC-diamonds were studied using first time.
