Resistivity and Band Gap Measurement of semiconductor is a versatile and useful system for physics and basic electronics laboratories. Band Gap can be measured by using Four Probe Method. This is one of the widely used methods for measuring the Resistivity and Band Gap of semiconductors. A collinear four-pr..

Frank Hertz ExperimentIntroduction  From the early spectroscopic work it is clear that atoms emitted radiation at discrete frequencies; from Bohr’s model, the frequency of the radiation n is related to the change of energy levels through DE=hn. It is then to be expected that transfer of energy to atomic electrons by any mechanism sho..

Gouys 's MethodApparatus for Measurement of Susceptibility of Paramagnetic Solids by Gouy’s MethodIn the Gouy’s method of susceptibility measurement, the solid sample in the form of a long cylinder (area of cross section A) is hung from the pan of a balance and is placed such that one end of the sample is between the pole-pieces of the magnet (fiel..

Ionization Potential Set-UpIntroduction  The electrons in the atoms have discrete stationary states. Franck and Hertz in 1914 describes the first observation of quantized excitation from one quantized state to another one year after N. Bohr published his theory of hydrogen atom. His method depends on detecting the on-set of inelastic coll..
