OBJECTIVES

To find the energy band gaps for different semiconductor diodes and LEDs

PRINCIPLE

At an absolute zero-degree temperature, semiconductors are pure insulators. As the temperature is increased thermal energy creates vibrations in the crystal lattice and a few electrons, which acquire sufficient vibrational energy break their covalent bond, become free, and move to the conduction band. The energy required to rapture the covalent bond is designated as energy gap EG and termed as energy gap or band gap energy.

KEY FEATURES

Built-In Heater: The heating element is built into the system and is powered by 12V input. The efficient heating mechanism heats the system to the required temperature in a few minutes with a minimum power requirement of 40W.
Modular Design: The modular design of the setup allows the testing of multiple diodes as well as different LEDs.
Built-In Voltage and Temperature Probe: All the necessary parameters to be measured are available directly on the setup itself.
