Head Korotchenkov Oleg Olexandrovich, Registration Date 28-01-2003 Organization Taras Shevchenko Kiev university popup.description2 The influence of ultrasonic treatment on diffusion processes in bulk silikon samples without dislocations is investigated. It is revealed that the ultrasonic processing stimulates diffusion processes in silicon at room temperature, i. e., the concentration K, Na and SiO is increased, and that of Ca unsignificantly decreases on a surface of the sample. The study of photothermoacoustic (PTA) effect in semiconductors is carried out. Intensities of group x-ray L(1, L(2,15, L(3 and L(4 emission lines of W, Re, Os, Ir and Pt of atoms are investigated.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
