Application of gallium oxide-based UV detector in complex topography and geological exploration

Abstract

In order to overcome the problem that the current geological exploration cannot detect complex geology effectively, a method of complex topographic geological exploration based on gallium oxide-based ultraviolet detector is proposed. On the surface of gallium oxide thin film, the dispersed aluminum nanoparticles are formed by a rapid thermal annealing method to prepare gallium oxide-based UV detector. The prepared UV detector is applied in the exploration of complex topography and geology, and the calibration conditions of geological exploration are determined. The appropriate UV detector probe is selected according to the calibration conditions. After the calibration conditions and probe are determined, the complex terrain is corrected by 3Mnnaert correction model, and the complex terrain is classified by multi-UV spectral band to realize the complex terrain geological exploration. The Maliba Reservoir in Yunnan Province with complex topography is selected as the experimental object. The experimental results show that the method can effectively explore the geological problems such as seepage, seepage stability, soil liquefaction, and uneven settlement of dam foundation in the experimental area.
