Conductivity and Real Structure of Cesium Hydrogen Sulfate–Phosphate Crystals

Superproton crystals obtained in the CsHSO 4 –CsH 2 PO 4 –H 2 O water‒salt system have been studied by electrical atomic force microscopy. Local I‒V characteristics for the Cs 3 (HSO 4 ) 2 (H 2 PO 4 ) and Cs 4 (HSO 4 ) 3 (H 2 PO 4 ) samples with different crystallographic orientations have been meas...

Summary:Superproton crystals obtained in the CsHSO 4 –CsH 2 PO 4 –H 2 O water‒salt system have been studied by electrical atomic force microscopy. Local I‒V characteristics for the Cs 3 (HSO 4 ) 2 (H 2 PO 4 ) and Cs 4 (HSO 4 ) 3 (H 2 PO 4 ) samples with different crystallographic orientations have been measured at 296 K, the conductivity anisotropy has been established, and the degree of dependence of the conductive properties on the sample composition has been demonstrated. Twin structures on cleavages have been considered, and their correlation with the atomic structure of monoclinic crystals have been investigated. Common features and differences between the atomic and real structures of the mixed crystalline phases and the effect of the hydrogen subsystems on their properties are discussed.
