Boltzman Constant Kit
Objective: Determination of Boltzmann Constant from forward I – V characteristics of Si-diode. Theory: The I – V characteristics of a semiconductor diode can be used to determine Boltzmann Constant accurately with the help of this simple equipment with ease and convenience. Diode equation can be written as If applied voltage V >> kT/e, the Boltzmann constant can expressed as: where is the slope of the straight line drawn between V and ln(I) The setup facilitates to measure the voltage and current across the sample in forward bias as tabulated below: From table above, plot a graph between V and ln (I) and Boltzmann constant can be calculated from the eqn (1) and slope of the straight line. Boltzmann Constant Kit consists of the following parts:
