Band Gap Measurement Setup

To study the temperature dependence of reverse saturation current in a junction diode and hence to determine the band gap of a semiconductor.

The following experiments to be performed :

1. Reverse saturation current I₀ and material constant η.
2. Energy Band Gap and temperature co-efficient of the junction voltage.

The trainer consists of :

1. Controlled Current Source.
2. Digital Voltmeter : 3 ½ Digit LED Display.
3. Digital Milliammeter :  3 ½ Digit LED Display.
4. Digital Temperature Indicator :  3 ½ Digit LED Display.
5. Temperature Controlled Oven.
6. Set of samples.
