The Investigation of Hybrid PEDOT:PSS/β-Ga2O3 Deep Ultraviolet Schottky Barrier Photodetectors

Abstract In this paper, the hybrid β-Ga2O3 Schottky diodes were fabricated with PEDOT:PSS as the anode. The electrical characteristics were investigated when the temperature changes from 298 K to 423 K. The barrier height ϕ b increases, and the ideality factor n decreases as the temperature increase...

description Abstract In this paper, the hybrid β-Ga2O3 Schottky diodes were fabricated with PEDOT:PSS as the anode. The electrical characteristics were investigated when the temperature changes from 298 K to 423 K. The barrier height ϕ b increases, and the ideality factor n decreases as the temperature increases, indicating the presence of barrier height inhomogeneity between the polymer and β-Ga2O3 interface. The mean barrier height and the standard deviation are 1.57 eV and 0.212 eV, respectively, after taking the Gaussian barrier height distribution model into account. Moreover, a relatively fast response speed of less than 320 ms, high reponsivity of 0.6 A/W, and rejection ratio of R 254 nm/R 400 nm up to 1.26 × 103 are obtained, suggesting that the hybrid PEDOT:PSS/β-Ga2O3 Schottky barrier diodes can be used as deep ultraviolet (DUV) optical switches or photodetectors.
