Import Energy Band Gap Of Pn Junction Diode — Buy in Bulk from Supplier in India

The Energy Band Gap of PN Junction Diode apparatus is a laboratory instrument designed to plot reverse saturation current against temperature under reverse bias conditions. It includes a DC regulated power supply ranging from 0 to 20 volts at 150mA, two moving coil meters (20V and 100μA ranges), and a temperature-controlled oven housing a germanium-type PN junction diode. The setup enables precise measurement of current variation as temperature increases.

The diode used is germanium, which has a typical band gap of 0.67eV at room temperature, making it suitable for demonstrating temperature-dependent semiconductor behavior. The oven provides controlled heating up to 150°C with a calibrated temperature knob, allowing students and researchers to observe the exponential rise in reverse saturation current. The system does not include digital data logging; measurements are taken manually via analog meters.

This instrument is primarily used in university physics and electronics labs for teaching semiconductor physics, particularly the relationship between temperature and intrinsic carrier concentration. Buyers include technical colleges, research institutes, and vocational training centres in Asia and Africa. Orders are typically for single units or small batches of 5 to 10 units. Packaging is in wooden crates with foam inserts. Lead time is confirmed upon order, and payment is usually via bank transfer against proforma invoice.
