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 coefficient of the junction voltage

 The trainer consists of :

  1. Crontrolled current Source
  2. Digital Voltmeter
  3. Digital milliammeter
  4. Digital temperature indicator
  5. Temp. control oven
  6. Set of samples
