Impedance anisotropy and quantum photocapacity of bio/inorganic clathrates InSe〈histidine〉 and gase〈histidine〉

Intercalated nanostructures of InSe〈histidine〉 and GaSe〈histidine〉 were formed. Phenomena of the negative capacitance and the quantum capacitance are visualized in the first nanostructure. The introduction of histidine between indium selenide layers leads to increasing of conductivity anisotropy ( σ...
