The structure and crystallisation of laser condensates vanadium deposited in oxygen atmosphere

The structure and crystallisation of laser condensates vanadium deposited in oxygen atmosphere

The phase composition and structure of films deposited by laser sputtering of V in oxygen atmosphere have been diagnosed by electron diffraction and transmission electron microscopy using "in situ" procedures as well as by consideration of bend extinction contours. It has been shown that a...
