We reported a method combining the gas-liquid interface method and inductively coupled plasma (ICP) to fabricate highly-ordered nanowire arrays on a 2 inch GaAs substrate. A large-area and highly-ordered SiO2 nanosphere monolayer was fabricated and the GaAs nanowire array was etched by ICP. The flow rates and ratios of the etching gases were studied. Finally, highly-ordered GaAs nanowire arrays with high quality surface morphology were obtained with the volumetric flow rates at 9 sccm and 21 sccm for BCl(3 )and N-2 gases, respectively. Reflectance of the samples was found to be consistently below 10%, the lowest being 3%. (C) 2018 The Japan Society of Applied Physics
