In this work, ZnO-based nanorod ultraviolet photosensors with large efficiency-gain product were obtained using the vapor cooling condensation method. To investigate the physical mechanism of the surface potential variation on the sidewall surface of the ZnO nanorods, the reabsorption rate of oxygen molecules, the Poisson equation, and the characteristic of current versus time under various oxygen ambiences were proposed to calculate the resulting surface potential variation. The results verified that both the oxygen reabsorption rate and the electron–hole recombination probability increased with an increasing oxygen concentration, and led to a decrease of the surface potential variation.
