Structural Imperfections of Crystals as a Result of Ion Implantation
The diffraction of X-rays has been studied in two-crystal interferometers, the crystals of which had equal interplanar distances and between the blocks of which a non-diffracting zone was formed as a result of ion implantation. Also the X-ray diffraction was studied in two-crystal interferometers, the interplanar distances of which were different and the non-diffracting zone between the crystals had zero width. It was shown in plane wave approximation that the Moiri: patterns should not be formed in case of former interferometers and necessarily arose with the latter type interferometers. kiCCJIenOBaHa nU@paKUIiR PeHTRHOBCKHX JlyYefi B ABYXKpHCTZiJIbHbIX EiHTep@epOMeTpaX, KPUC-TaJIJIbI KOTOpbIX IIMCWT OJ@iHaKOBbIe MeXnJIOCKOCTHbIe paCCTORHHR Ii MeXny 6JIOKaMH KOTOPbIX B @paKUAR PeHTreHOBCKUX JIyWfi B nBYXKPHCTZiJIbHbIX EiHTep@epOMeTpaX, MeXnJIOCKOCTHble PaCCTOXHIia KpHCTaJIJIOB KOTOPbIX OTJIHYBWTCR APYr OT npyra, HO IIIKpIiHa HeAH@parHp)'WI4Ze% 30HbI MeXnY B IUIOCKOBOnHOBOM npu6nume~uu IIOKa3aH0, YTO OT IIepBOrO HHTep@epOMeTpa MyanOBbIe KaPTUHbI p e z ~y n b ~a ~e H O H H O ~~ aMnnaHTaquu 06pa30ea~a Henu4parupymqaa 3 o ~a .
