Abstract

The structural characteristics of Ga₂O₃ nanowires and the sensitivity of Ga₂O₃ extended gate field effect transistor (EGFET) pH sensors are investigated. The Ga₂O₃ nanowires are prepared using a vapor-liquid-solid (VLS) mechanism. The results show that the nanowires correspond to β-Ga₂O₃ phase and single crystals. The β-Ga₂O₃ nanowires were active materials in the EGFET pH sensor. The resulting EGFET pH sensor containing β-Ga₂O₃ nanowires exhibits high detection of properties (14 μA · pH^-1). The β-Ga₂O₃ nanowires are a candidate material for pH sensor.
