Originální abstrakt
In the present communication, the conductivity of the single crystal methylammonium lead bromide as a function of temperature is studied. As a result, the activation energies for the dark/light conditions were determined. Interestingly, when the light illumination is applied, depending of the applied bias voltage, the complex conductivity response on the temperature changes was observed. Depending on the electrical field applied, the material follows two behaviors: first is typical of semiconductors and the second one and non-Arrhenian behavior, which is distinctive for metals. This is, for the best of our knowledge, the first observation of this unique property of single crystal methylammonium lead bromide perovskite.
