Pour a thin film bismuth telluride is coated onto a substrate Poly Impact Middlesbrough. By R. F. magnetron sputtering sterling by blowing BUSINESS Mustaine telluride (99.99%) in diameter, 3 inches, the distance between the target and substrate 50 mm. The earlier pieces. Work to install Polycarbonate sheet has led to Imphal Mid Ultra Sonic in alcohol for 15 minutes to remove the dirt and clean the surface of the workpiece. Be the electric power supply to the 45-watt range Bi2Te3 pressure in the coating surface 2 × 10-5 mbar and pressure used in the coating film is 5x10-3 mbar using argon gas. 30 minutes from time in the coating is then baked at different temperatures (300, 350 and 400 ° C) under atmospheric pressure of nitrogen gas (6 x 10-3 mbar) for one hour
to film. The crystal structure was analyzed The tester diffraction of X-rays (X-ray diffraction, XRD make Bruker model D8-Discover), which uses X-rays CuKα wavelength 1.54056 Angstrom, electron microscopy, SEM resolution (Field Emission Scanning Electron Microscope,. FE-SEM model JSM-7001F) using a probe Secondary Electron Detector burst shooting mode Secondary Electron Image (SEI) and connect to the device element analysis-oriented energy (Energy Dispersive X-Ray Spectrometer, EDS) by impressions. energy spectrum of elements with specific and disproportionate amount of each component. Measuring thermoelectric properties of dielectric films using a measure electrical properties (Seebeck Coefficient / Electrical Resistance Measurement System, ZEM-3 All ULVAC-RIKO).
