Meissner Effect
The Meissner effect is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state.
Semiconducting behaviour of thermistor
This demonstaration shows the semiconducting behaviour of a thermistor. A thermistor is a temperature-sensing element composed of semiconductor material which
Electron diffraction
This interesting demonstration utilizes a highly evacuated electron diffraction tube to show the wave behavior of electrons. The electrons are
Hall effect in Semiconductor materials
When a magnetic field is applied perpendicular to the direction of flow of charge carriers, in a semiconductor material, charge
Phonon modes in a linear lattice
This demonstration is specifically based upon the properties of phonons. A diatomic chain with well defined periodicity is used as
Close packing of atoms
Table tennis balls that are glued together can be stacked on top of one another showing the two most important
