Abstract

This work explores a simple and inexpensive method for growing high-density gallium oxide (β-Ga₂O₃) nanowires at high temperatures (~1000 °C) for UV detection applications. The method involves heating and oxidizing pure gallium in the presence of trace oxygen, potentially scalable for large-scale production. The study characterizes the nanowires morphologically, structurally, electrically, and optically, examining the influence of density on their properties to optimize UV light detection. Using a 5nm Ag catalyst enhances nanowire growth, density, and photocurrent response.
