Electrical Performance

Under the following typical test conditions:

Sample power consumption less than 1mV; under these conditions, excite to the recommended current and voltage as specified in the system configuration.

Sampling Temperature: 295K

Sample holder non-leakage current

Each test lead resistance is 25Ω

The voltage efficiency for measuring resistivity (V_out / V_in) should be 0.1.

Sample Shape Correction Factor: 1

Magnetic field and sample thickness test uncertainty is within 1%.

Magnetic field/sample thickness is 1T/mm, note that the measured carrier concentration ratio is approximately this value. Therefore, stronger magnetic fields and thicker samples cannot increase the testing range.
