The invention relates to a method for deposition of thermoelectric material on a substrate. Nanoparticles of thermoelectric material are synthesized and provided in such a way that the printing operations (inkjet and laser printing processes) can be implemented optimally, yet with the possibility of pressureless sintering thereafter. Pressureless sintering leads to dense layers, endowing the material with the mechanical and thermoelectric properties obtained by other methods (especially fusional and sintering methods with pressure). To prevent the nanoparticles reacting with one another during printing, they are coated with a molecular layer (monolayer) that prevents their aggregation and so leads to their homogeneous distribution in the ink (colloidal solution) or that renders the powders non-electroconductive for the purposes of laser printing, allowing them to be electrostatically charged so as to operate as toners. After the printing operation, this molecular layer is removed by a sintering treatment that confers a highly reactive surface on the particles. Pressureless sintering leads to good bonds between and among the nanoparticles.
