China Wholesale Liquid Conductivity Pricelist – LEEM-10A Experimental Apparatus of PN Junction Characteristics – Labor Detail:

Experiments

1. The relation between the PN junction diffusion current and the junction voltage is measured, and this relation shall be proved to follow the exponential distribution law through data processing;

2. The Boltzmann constant is measured more accurately(The error shall be less than 2%);

3. Learn to use operational amplifier to form a current-voltage converter to measure the weak current from 10-6A to 10-8A;

4. The relation between PN junction voltage  and temperature is measured and the sensitivity of junction voltage with temperature is calculated;
