The Energy Band Gap Apparatus is used to determine the energy band gap (E_g) of a semiconductor by studying how the reverse saturation current of a PN junction diode changes with temperature. Students heat the diode in the built-in oven, record current at rising temperatures, plot log(I_s) against 1/T, and calculate the band gap from the slope — the standard degree-level solid-state physics experiment.

Specifications

Feature	Details
Experiment	Determination of energy band gap of a semiconductor (PN junction diode)
Method	Reverse saturation current vs temperature; log(Is) vs 1/T plot
Built-in	Temperature-controlled oven, diode holder with thermometer well, digital meters, regulated DC supply
Panel	Screen-printed circuit diagram on sturdy instrument case, ON/OFF with mains cord
Best for	B.Sc / M.Sc physics practicals, engineering physics labs, polytechnic labs
SKU	SAM-EBG-01 · Made in Ambala, India

How the Experiment Works — 3 Steps

1. Heat
Place the diode in the oven and raise temperature in steps, reading it on the thermometer.

2. Measure
Record reverse saturation current I_s at each temperature on the built-in meter.

3. Plot & Calculate
Plot log(I_s) vs 1/T — the straight-line slope gives the energy band gap in eV.

Frequently Asked Questions

Who manufactures Energy Band Gap Apparatus in Ambala?
Samtech Instruments, established 2002 at HSIIDC Industrial Estate, Ambala Cantt, manufactures energy band gap apparatus and complete physics lab equipment under the JAYSEE brand, supplying colleges across India and 30+ countries.

Which semiconductor is used in the experiment?
A germanium or silicon PN junction diode — the experiment measures its reverse saturation current at different temperatures to find the band gap (≈0.7 eV for Ge, ≈1.1 eV for Si).

Is it suitable for B.Sc and engineering practicals?
Yes — this is the standard solid-state physics experiment in B.Sc, M.Sc and first-year engineering syllabi across Indian universities.

Do you supply in bulk for college labs and tenders?
Yes — bulk/tender pricing for universities, polytechnics and distributors. GST invoice and support included.
