Band Gap of Semiconductor

Aim

To determine the band gap in a semiconductor using a PN junction diode.

Apparatus

  • 01 Energy band gap kit with a PN junction diode mounted inside a temperature-controlled electric oven
  • 02 Microammeter
  • 03 Voltmeter
  • 04 Mercury thermometer mounted on the front panel to read the oven temperature

3D simulations run slower without it. Turning it on is recommended.

The simulations need WebGL 2, which isn’t available in this browser right now. Turning on hardware acceleration usually brings it back; if not, update the browser or the graphics driver.

3D simulations are running with hardware acceleration. Nothing to change.

On a college lab computer this setting may be locked. If so, ask the lab in-charge.
