Аннотация
The orientation relationships between the low-temperature monoclinic semiconductor acanthite α-Ag2S and the high-temperature body-centered argentite β-Ag2S are determined based on high-temperature X-ray diffraction and high-resolution transmission electron microscopy (HRTEM) data on silver sulfide. It is found that, in contrast to acanthite, the possible distances between silver atoms in cubic argentite are too small to allow Ag atoms to occupy metal sublattice sites with a probability of 1. It is shown that the (010) and (001) atomic planes of acanthite are parallel to the (1\(\bar {1}\)0) and (221) planes of argentite, respectively. The found orientation relationships between acanthite and argentite are important for understanding the physical operation of the Ag2S/Ag heteronanostructure, which is considered as a potential basis for designing resistive switches and nonvolatile memory devices.
