China Wholesale Voltmeter Factories – LEEM-10 Experimental Apparatus of PN Junction Characteristics – Labor Detail:
Experiments
1. At the same temperature, measure the forward volt-ampere characteristics of the PN junction and calculate the Boltzmann constant;
2. The forward current I remains unchanged, the V-T curve of the forward voltage of the PN junction is mapped, the sensitivity is calculated, and the band gap width of the measured PN junction material is estimated;
3. Application experiment: use a given PN junction to measure unknown temperature;
4. Innovative experiment: According to the experimental data, estimate the reverse saturation current Is of the PN junction.
5. Exploratory experiment: Observe the influence of the size of the composite current.
