In this study, we fabricated in-plane thermoelectric micro-generators (4 mm times 4 mm) based on bismuth telluride thin films by using flash evaporation method. The thermoelectric properties of as-grown thin films are lower than those of bulk materials. Therefore the as-grown thin films were annealed in hydrogen at atmospheric pressure for 1 hour in a temperature range of 200 degC. to 400degC. By...
Encapsulated Ag(Ti) films on oxidized silicon were obtained by nitridation of Ag(19 at.% Ti) alloys in a flowing NH3 ambient at temperatures between 400-700??C for various times. Upon annealing at temperatures ?? 350??C Ti segregates to the surface and alloy/SiO2 interface. At the free surface Ti reacts with the ammonia to form a TiN(O) surface layer. The Ti that diffuses to the interface dissociates...
Fe-M-(O,F) (M=Si, Mg, Y, Zr, Ca, Al) films were prepared by co-sputtering of Fe and ceramic targets. These films have a network-like structure consisting of fine metallic grains of diameter 50 to 100 ?? and ceramic-like boundaries. Those films that consist of bec Fe grains have soft magnetic properties and low magnetostriction in the as-deposited state. Their permeability has good frequency response,...
