مستخلص: Quasi one-dimensional materials are technologically very important due to their extraordinary properties. The properties are enhanced when these materials are exfoliated into single or few layers. In this work, we present the laser etching of TiS3 nanoribbons synthesized by chemical vapor transport technique. The experiments were carried out using the TiS3 nanoribbons with thicknesses ranging from 100 to 150 nm. These nanoribbons were transferred on a silicon substrate via mechanical exfoliation technique prior to the laser treatment for the etching process followed. The resulting etching depth was in the range of 20–25 nm with no oxidation. Through the experiments, it was found that the etching depth was independent of the initial thickness of the nanoribbons, which suggests that if samples had a smaller initial thickness, a monolayer can be obtained. We also observed significant (up to 3–4 nm) improvement of the surface roughness of the etched samples, which makes the laser etching technique promising for the development of flexible, efficient, and reliable optoelectronic devices.
