The thermocouples are formed of Pt and Au strips, wide, on glass microscope slides. The thermoelectric voltage is measured as indicated.
Measured thermopower as a function of a Pt film thickness . The thickness of the Au film was fixed at . The line is a best fit to the data.
Measured as a function of the inverse Pt film thickness . The full line is a best fit to the data, and the dashed line shows the linear behavior of , which is expected for films much thicker than .
Measured thermoelectric power for samples of different Pt film thickness for a fixed Au film thickness of .
