Abstract
Cs3(HSO4)2(H2PO4) and Cs4(HSO4)3(H2PO4) superprotonic crystals have been investigated by conductive atomic force microscopy at increasing temperature. Local I‒V characteristics have been measured and an increase in the conductivity of the Cs3(HSO4)2(H2PO4) and Cs4(HSO4)3(H2PO4) crystals at 413‒453 K by two and three orders of magnitude, respectively, has been detected. Differences in the conductive characteristics of the crystals of different compositions in the vicinity of the phase transition are shown. Information on topographic and electrical features of the crystalline phases before and after exposure to temperature and electric fields has been obtained. The effect of external factors on the stability of the surface microstructure is evaluated. Possible mechanisms of the structure and phase transformations in the isostructural compounds with different ratios of sulfate and phosphate groups are discussed.
期刊介绍:
Crystallography Reports is a journal that publishes original articles short communications, and reviews on various aspects of crystallography: diffraction and scattering of X-rays, electrons, and neutrons, determination of crystal structure of inorganic and organic substances, including proteins and other biological substances; UV-VIS and IR spectroscopy; growth, imperfect structure and physical properties of crystals; thin films, liquid crystals, nanomaterials, partially disordered systems, and the methods of studies.
