Application of X-ray pendulum fringes for investigation of electron irradiated semiconductors

In the present work, a two-block X-ray interferometer (wedge-thick crystal) was used to study distorted regions of the crystal structure formed in a wedge-shaped plate as a result of its irradiation with electrons with energies of 0.5–1.0 MeV. Based on the detected mixtures of the absolute positions of the pendulum bands, the sizes of strongly distorted regions of the crystal under study were estimated.
