Product Code : EL-AET-1460
Jlab Export is a leading Determination of Energy Band Gap in Semiconductor Diode Manufacturer,and suppliers in India
Determination of Energy Band Gap in Semiconductor Diode (code EL-AET-1460) is an analog electronics trainer for finding the energy band gap of a P-N junction diode from the way its reverse saturation current changes with temperature. The diode is warmed in an electrically heated oven, and the current is read on a 3½-digit digital microammeter. JLab (Jain Laboratory Instruments Pvt Ltd) builds the unit in Ambala, India.

Choose this trainer when you want the current shown on a digital microammeter and a thermometer scale running to 110 °C. The Energy Band Gap of PN Junction Diode apparatus has an oven with a temperature control system, and the Energy Band Gap Apparatus has a variable supply with moving coil meters on an aluminium front panel.
What Is the Band Gap Trainer Used For?
The trainer is used for the band gap experiment in undergraduate semiconductor physics and electronics laboratories. Students take the diode through a series of temperatures in the oven, record the reverse saturation current at each one, draw the current–temperature characteristic and calculate the band gap of the diode material from it.
What to Specify When Ordering
- Model — this trainer or one of the other band gap set-ups compared above.
- Number of units for your laboratory.
- Other semiconductor trainers for the same course, such as the diode trainers linked below, which can be quoted on the same enquiry.
Frequently Asked Questions
What is the energy band gap?
It is the energy an electron needs to move from the valence band to the conduction band of a semiconductor. It is a basic property of the material and largely decides how strongly the semiconductor conducts at a given temperature.
Why does the reverse saturation current change with temperature?
In a reverse-biased P-N junction, the small reverse saturation current is carried by electron–hole pairs generated thermally across the band gap. A hotter junction generates many more of them, so the current rises steeply with temperature, and the size of the band gap governs how steeply.
How is the band gap worked out from the readings?
From a graph. Over the working temperature range, a plot of the logarithm of the reverse saturation current against the reciprocal of the absolute temperature is close to a straight line, and the band gap is calculated from its slope.
What documentation is supplied?
Detailed operating instructions giving the object, theory, design procedures, report suggestions and book references for the experiment.
What information is needed for an export quotation?
The number of units, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling instructions, and the tender reference if you are buying against a tender.
Who manufactures this trainer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of physics and electronics laboratory apparatus, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The band gap trainer is assembled at the company’s own works instead of being sourced from a trader, so universities, colleges, dealers and importers deal with the maker directly, every unit is visually inspected before it leaves, and repeat orders and spares are handled by the same works. The company is registered under GSTIN 06AADCJ9848D1ZE and holds Legal Entity Identifier 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — for example Chile in South America, Sweden in Northern Europe, Bhutan in South Asia, Indonesia in Southeast Asia and the Dominican Republic in Central America and the Caribbean. Tender information is on the JLab lab tenders page.
