Abstract	Hydrothermal growth methods allow for low-temperature synthesis of ZnO nanowires (NWs) directly on a variety of novel substrates required for proposed flexible substrate applications such as power-harvesting fabrics [1]. Although hydrothermal growth opens up a new realm of application possibilities, a major drawback of this method is growth time — up to 20 hours or longer have been reported as necessary to yield desired NW morphologies [2]. The use of microwave heating of the nutrient solution has recently been reported to speed the growth process [3]. Although hydrothermal growth temperature has been reported to be a critical process variable [4], the conventional microwave used previously [3] did not offer a direct method of controlling process temperature. Instead, indirect control of growth temperature was attempted by microwave power level adjustment. Other typical microwaves change power level through variations in duty cycle. In this work, a research grade microwave oven, equipped with integrated temperature control, was used to systematically investigate the impact of growth temperature, growth time, and solution concentration on ZnO NW length, diameter, aspect ratio, growth orientation, density, and wire morphology.
