Product Description

Energy Band Gap By Four Probe Method

Experiment consists of the following :

Probes Arrangement : It has four individually spring loaded, coated with Zn at the tips. The probes are collinear and equally spaced. The Zn coating & individual spring ensure good electrical contacts with the sample. The probes are mounted in a bush which ensure a good electrical insulation between the probe. A spacer near the tips is also provided to keep the probes at equal distance. The whole arrangement is mounted on a suitable stand and leads are provided for current and voltage measurements.

Features :

  • Sample : Ge (Germanium) crystal in the form of a chip slice.
  • Oven : It is a small oven for the variation of temperature of the crystal from room Temperature to about 200Deg C. Operating Temperature is 180DegC
  • Four Probes Set-up : (Measuring Unit)-LCD Display for all Parameters
  • Soft Press Keys for Menu
  • USB Interface
