Effect of Impurity Precipitations on the Anomalous X‐Ray Transmission in Heavily Arsenic‐Doped Germanium

Experimental data of quantitative studies of the integral characteristics of anomalous X‐ray transmission are given for germanium with different dislocation densities, doped with arsenic up to a concentration of ≈4 × 10 19 at/cm −3 at various stages of existence and decomposition of the solid solution. The state of solid solution was controlled by electrophysical measurements and X‐ray topographs (Borrmann's method). On the basis of the results obtained some conclusions are drawn about the character of the disturbances generated by the above mentioned decomposition of the solid solution. Particularities of the solution behaviour are considered when the concentration of arsenic is near the limit.
