A resistance change effect in perovskite CH3NH3PbI3 films induced by ammonia.
The resistance of the perovskite CH3NH3PbI3 film was found to decrease significantly in seconds when the film was exposed to an NH3 atmosphere at room-temperature, and recover to its original value in seconds when out of the NH3 environment.
