(abstract)

We investigate the controlled thermal oxidation of individual TiS3 nanoribbons and its influence on the optoelectronic properties of TiS3-based photodetectors. We study the oxidation of TiS3 in powder form and single nanoribbons deposited on a glass substrate. We find that an individual TiS3 nanoribbon converts to crystalline TiO2 in approximately 5 minutes when kept at temperatures larger than 300 ℃. Control experiments performed on TiS3 nanoribbons fully encapsulated between hBN flakes confirm that the direct contact between TiS3 and air is necessary for the oxidation process to happen. After establishing the change in material properties we demonstrate the controlled oxidation of a TiS3 nanoribbon photodetector that allows tuning the cut-off wavelength and sensitivity of the device.
