(color online) Synthesis and characterizations of TiS nanoribbons. (a) The TiS crystal structure. Ti atoms are covalently bonded to six S atoms forming triangular prisms which are stacked to make chains. (b) The optical microscopy image of TiS nanoribbons on an SiO /Si substrate. (c) The SEM image of TiS nanoribbons. Inset: single TiS nanoribbon. (d) The EDX spectrum of TiS nanoribbons with the atomic ratio of Ti/S of 1:3. (e) The Raman spectrum of the individual TiS nanoribbon on SiO /Si substrate at room temperature using a 532-nm laser source.
