Özet:

 Aligned arrays of anatase TiO2 nanotubes on a Ti sheet were created by a dual-step electrochemical anodizing treatment and extended calcination step at 400 oC under an ambient atmosphere, as shown in FESEM images. A diffuse reflectance approach was adopted to measure the energy bandgap is 3.42 eV. The nanotubular pattern is utilized to assemble a fast-response UV photodetector as recognized by Metal-Semiconductor-Metal assembly. The photodetector exhibited excellent UV sensitivity, attributed to the anatase phase of the TiO2 nanotube arrays. The photodetection testing confirmed adept detection of UV photon illumination with excellent stability and repeatability. The UV photodetection performance exhibited a current gain value of 6, a response time Ton of 0.98, 0.97, and 0.92 seconds, and a recovery time Toff of 0.97, 0.95, and 0.94 seconds at a biased potential of 3, 4, and 5 V, respectively. The findings of this research corroborate the promising nature of the UV photodetector fabricated utilizing anatase nanotube arrays, exhibiting its immense potential for applications in the UV spectrum.
