摘要：
Well-aligned ZnO nanorod array films with various morphologies are prepared on Au/Ti interdigital electrodes (IDEs) by changing the concentration of growth solution using a mild hydrothermal process. A feasible mechanism for controlling their growth is discussed. The UV-enhanced gas sensing results reveal that smaller rod diameter and higher density array can improve the response of sensors based on ZnO nanorod array films to O-2 gas, while slower desorption of O-2 molecules on the nanorod surfaces is found for the higher-density array films.
