The metal chalcogenide thin film includes a transition metal element and a chalcogen element, and at least one of the transition metal element and the chalcogen element having a composition gradient along the surface of the metal chalcogenide thin film, the composition gradient being an in-plane composition gradient. The metal chalcogenide thin film may be prepared by using a manufacturing method including providing a transition metal precursor and a chalcogen precursor on a substrate by using a confined reaction space in such a manner that at least one of the transition metal precursor and the chalcogen precursor forms a concentration gradient according to a position on the surface of the substrate; and heat-treating the substrate.

A method for a workpiece comprising a material composed of a base material and an additive is disclosed, the method including spreading a granular material in superimposed layers. The granular material contains the base material and an organic binder. An ink contains a solvent for dissolving the binder, and a suspension of the additive. Using the ink, patterns are printed onto individual layers. The ink dissolves the binder in the region of the patterns, and introduces the additive in the region of the patterns. The patterns in the layers together produce a three-dimensional shape of the workpiece. The solvent is expelled so that the granular material is connected by the binder and the additive is fixed. Granular material unwetted by the solvent is removed to reveal the green compact of the workpiece. The green compact is thermally treated to convert the base material and the additive into the material.
