Model No:SP-FEGK
In Forbidden Energy Gap Kit, the Forward biased voltage of a silicon/germanium diode or LED is studied as a function of temperature. The results can be used to evaluate Forbidden Energy Gap of Silicon, Germanium and L.E.D. The kit is self contained and needs no additional equipment.,Current and Voltage are measured using digital Micro- ammeter and digital Voltmeterrespectively. The diode under investigation is to be connected to the main unit. With the help ofHot air oven and oil, temperature of sample is raised and corresponding voltages are measured.From Slope (a) and intercept (b) of graph between voltage and temperature, Energy Gap is calculated using eqn (2).
