Enhanced Performance of NiO/β-Ga₂O₃ Heterojunction Photodetector via Piranha Treatment and Its Application to Solar-Blind Communication
In this work, we demonstrated a high-performance NiO/ \beta -Ga2O3 heterojunction photodetector using piranha solution pretreatment technology. After treatment, the NiO/ \beta -Ga2O3 heterojunction exhibited an excellent electrical performance, including a higher on/off ratio of 1\times 10^{{7}} ,...

| description | In this work, we demonstrated a high-performance NiO/ \beta -Ga2O3 heterojunction photodetector using piranha solution pretreatment technology. After treatment, the NiO/ \beta -Ga2O3 heterojunction exhibited an excellent electrical performance, including a higher on/off ratio of 1\times 10^{{7}} , a lower reverse current of 0.28 pA, and an improved ideal factor. Additionally, the solar-blind detection performance of treated sample was significantly enhanced, including a 2900% increase in photo-to-dark-current ratio (PDCR), a 140% increase in responsivity, and a 900% increase in detectivity. Notably, excellent rise time and decay time were observed to be 60 and 50 ms after treatment, demonstrating an impressive reduction of 97% and 98%, respectively. This fast response characteristic has a wide range of applications. Thus, we conducted an optical communication test based on an original solar-blind communication system. Data transmission was successfully achieved ten times with a short sampling time of 100 ms. These results illustrate the effectiveness of piranha solution pretreatment in elevating the performance of Ga2O3-based heterojunction photodetector. |
