LEEM-10 Experimental Apparatus of PN Junction Characteristics

Experimental Apparatus of PN Junction Characteristics 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.   The main technical parameters 1. A variety of PN junctions with packaging, including silicon tubes, germanium tubes, NPN transistors, etc.; 2. The current output range is 10nA～1mA, adjustable in 4 sections, fine adjustment: minimum 1nA, driving voltage About 5V, skip words ≤ 1 word/min;
