【Abstract】 The transparent conducting SnO 2:F thin film is extensively used in displaying and energy-conversion technology. In this paper SnO 2:F thin films were deposited by ultrasonic spray pyrolysis technology. The dependence of structure, morphology and opto-electrical characteristics on substrate temperature, concentration in reaction solution were investigated by XRD, UV/Vis, SEM and AFM. The results show that the microstructure and resistivity of SnO 2:F thin films are intensively dependent on substrate temperature. Through optimization of the concentration in reaction solution, transparent low-resistance SnO 2:F thin film is deposited successfully.更多还原
