Application of Nanostructured TiO 2 in UV Photodetectors: A Review

Abstract As a wide‐bandgap semiconductor material, titanium dioxide (TiO 2 ), which possesses three crystal polymorphs (i.e., rutile, anatase, and brookite), has gained tremendous attention as a cutting‐edge material for application in the environment and energy fields. Based on the strong attractiveness from its advantages such as high stability, excellent photoelectric properties, and low‐cost fabrication, the construction of high‐performance photodetectors (PDs) based on TiO 2 nanostructures is being extensively developed. An elaborate microtopography and device configuration is the most widely used strategy to achieve efficient TiO 2 ‐based PDs with high photoelectric performances; however, a deep…
