Resistivity vs. Temperature of a Superconductor

• Calibrate a transducer (silicon diode) for low-temperature measurements and measure temperatures down to that of boiling liquid nitrogen. • Accurately measure very low voltages, including techniques for reducing or compensating for electronic noise. • Identify the source of and compensate for systematic error(s) in measurements. • Examine the behavior of a high-Tc superconductor sample during the transition between the superconducting and normally-conducting states. • Report the results of your measurements in a format appropriate for submission to a journal for publication.
