Abstract
This letter presents vapor-liquid-solid growth of β-Ga2O3 nanowires (NWs) on cost-effective SiO2/Si template and the fabrication of β-Ga2O3 NW field emitters. It is found that the β-Ga2O3 NWs grown at 950°C are structurally uniform, defect free, and well-oriented with pure monoclinic structure. It is also found that turnon fields are 2.0, 3.9, and 5.8 V/μm whereas field-enhancement factors β are 1890, 2760, and 4489, for the samples grown at 850°C, 900 °C, and 950°C, respectively. For the sample prepared at 950°C, it is found that we could further reduce the turnon field from 2 to 1.2 V/μm whereas enhance the field-enhancement factor β from 4489 to 6926 by ultraviolet irradiation.
