Product Code : SCL-WAE-14577
Indian Lab Suppliers supplies the Energy Band Gap Apparatus (Product ID: 14577) as part of its work and energy range. A bench apparatus for finding the energy band gap of a germanium or silicon diode from how its reverse saturation current changes with temperature.
Quick Answer
The diode is reverse-biased from the built-in regulated DC supply and heated in a temperature-controlled arrangement, while digital meters read the reverse current and voltage and a temperature sensor gives the diode temperature. Because the reverse saturation current rises steeply with temperature, roughly as exp(−Eg/kT), a graph of log Is against 1/T is a straight line whose slope gives the band gap Eg. The unit comes fully assembled with a diode mount and leads. Diode type (germanium or silicon), meter ranges, supply range, heating method and sensor type vary by model, so please confirm them at quotation.

Where This Is Used
Used in engineering college and university physics labs for semiconductor practicals, alongside the PN Junction Diode Apparatus – 2 Meter (Product ID: 14596) and the Digital Zener Diode Apparatus (Product ID: 14659). The heating chamber gets hot, so let it cool before changing the diode. Browse the full Work and Energy range or related Electrical and Electronics products.
