96 Experiment 15 Electrical Resistivity of Semiconductors Apparatus Four probe assembly with oven, semiconducting sample, current source, voltmeter etc. Objective: To study the temperature variation of electrical resistivity of a semiconducting materials using four-probe technique and determine the bandgap of the semiconductor. Theory The Ohm' s law in terms of the electric field and current density is given by the relation, = J E ρ (1) where is electrical resistivity of the material. For a long thin wire-like geometry of uniform cross-section or for a long parellelopiped shaped sample of uniform cross-section,
