Chiarella, P. Ferro, F. Licci, M. Barra, M. Biasiucci, A. Cassinese, R. Vaglio] We describe the preparation, structural and transport properties of CH3NH3SnBr3 organic-inorganic hybrid films (500nm thick), which crystallize as cubic perovskites. They were deposited by single source thermal ablation technique, in a 10-6mbar vacuum chamber on glass, polymeric and crystalline substrates. X-ray diffraction proved that they were well crystallized and c-axis oriented. Resistivity measurements as a function of temperature showed a semiconductor behaviour. The activation energy, ΔE, was estimated by fitting the linear portions of the resistivity vs. temperature plots and was found to be (0.30±0.01) eV in the 260-230K temperature interval. A significant change in resistivity was observed at a low temperature T=225K in coincidence with the structural distortion in the Sn-Br-Sn chains. A field effect device was used to determine the charge carrier type and mobility as a function of temperature and field. The charge carriers were hole type. Their mobility at room temperature was about 10-5cm2V- 1s- 1. It increased by two orders of magnitude at 320K and exhibited an almost exponential dependence on the applied gate voltage.
