Abstract

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.

食人鱼处理增强NiO/β-Ga₂O₃异质结光电探测器性能及其在日盲通信中的应用

在这项工作中，我们展示了一种高性能的NiO/ $\beta $ -Ga2O3异质结光电探测器，采用食人鱼溶液预处理技术。经过处理后，NiO/ $\beta $ -Ga2O3异质结表现出优异的电学性能，包括较高的通断比（$1\ × 10^{{7}}$）、较低的反向电流（0.28 pA）和改善的理想因子。此外，处理后的样品的太阳盲检测性能得到了显著提高，其中光暗比（PDCR）提高了2900%，响应率提高了140%，探测率提高了900%。值得注意的是，治疗后的上升时间和衰减时间分别为60 ms和50 ms，分别减少了97%和98%。这种快速响应特性具有广泛的应用范围。因此，我们在原始的太阳盲通信系统的基础上进行了光通信测试。数据传输成功10次，采样时间短，仅为100 ms。这些结果说明了水虎鱼溶液预处理在提高ga2o3基异质结光电探测器性能方面的有效性。
