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