In this work the relation between the morphology, chemical composition and photoelectric properties of vertical ionotronic nanostructures based on layered semiconductor InSe and ionic RbNO3 salt was investigated. It is established that nanostructures consisting of 2D InSe layers, ultrathin layers of In2O3 oxide and annular nanostructures of the ionic salt, which are located in the (0001) planes of InSe crystal periodically along main crystal axis, have a maximum photosensitivity. The connection between the heterogeneous morphology and the spectral distribution of photoconductivity for the ionotronic nanostructures formed on the basis of GaSe and InSe crystals and ionic MeNO3 salts (Me = K, Rb) is established. Impedance spectra, spectral distribution of photosensitivity and morphology of the surfaces of vertical ionotronic structures, formed on the basis of 2D layered semiconductor n-InSe and ionic RbNO3 salt has been investigated.
