Abstract

In this study, we investigate the influence of ultraviolet–ozone (UV–O3) treatment on the photodetection properties of multilayer-MoS2 films. The MoS2 thin film photodetectors were fabricated using a sequential spin coating process at low temperature. As UV–O3 exposure time was increased, a significant enhancement in the photodetector performance at both ultraviolet and visible-light ranges has been observed. After 5 min of exposure to UV–O3, a 99% increase in the photoresponsivity to UV radiation, at wavelength of 320 nm, was observed under light intensity of 300 µW cm−2. This remarkable improvement in UV detection was accompanied by a noteworthy enhancement through the whole visible range with a maximum responsivity of 128 A/W and a highest detectivity of 1.3 × 1012 Jones at 580 nm irradiation. On the infrared side, a drop of 13.6% in responsivity and around an order of magnitude reduction in detectivity were noticed for 750 nm irradiation after the 5 min UV–O3 treatment. All built detectors showed reliable photo-switching properties with response time of 0.22 s. Raman spectroscopy and X-ray photoelectron spectroscopy analysis suggest that the significant improvement of optoelectronic properties is caused by the passivation of localized Sulfur vacancies by O2 or oxygen ions that bond chemically with MoS2. Such findings provide a quick and simple route for modulating the optical properties of MoS2-based optoelectronics through a surface treatment.
