Laser-sintered Si, Ge and SiGe nanoparticle thin films are investigated concerning their applicability to thermoelectrics. A mesoporous meander-like structure is the characteristic feature of the resulting films. To adjust the doping in the films a new wet-chemical method is developed. The complex structure of the films requires advanced methods for the determination of the thermal conductivity, for which spatially resolved Raman spectroscopy is used. The thermoelectric figures of merit obtained for the laser-sintered films are at least comparable to other SiGe materials.     «
