Resistivity of semiconductors by four probe method at different Temperatures & Determination of Band gap.
The experiment consists of the following :
- Four Probe Arrangement
- Oven (upto 200ºC)
- Sample: Ge Crystal mounted
- Four Probe Setup
- Constant Current power supply digital Accuracy: 0.25% of the reading 1 digit Load Regulation: 0.03% for no load to full load
- 1 digit Impedence: 1 M/ohm
- Display: 3½ digit, 7 segment LED (12.5mm)height with auto polarity and decimal indication.
