You work as an engineer in a company and you have been given the assignment of
measuring the electrical conductivity and the band gap (Eg) of a new intrinsic semiconductor
material at 20 and 100 °C. You cut this material in the form of a rectangular prism with a
length of 30 cm, a width of 1 cm and a thickness of 2 cm, and you applied a potential
difference of 1 V by placing electrodes on the faces shown in the figure. In this case, you
measure a current of 0.8A at 20 °C and 12A at 100 °C. According to this information
calculate the electrical conductivity of the material at 20 and 100 °C and

- A pn diode is a semiconductor device in which, unlike in a metal, the current flow is due not only to negative electron charge flow but also due to positive charges. The positive charges are usually referred to as holes, as they are really "deficit" in the negative charge distribution. The semiconduction material (usually silicon with Er = 11 or gallium arsenide with e, impurities are added. Initially, the physically important region on the p side contains a density p+ of positive charges per unit volume, whereas the n region contains a negative charge density p-. When they are brought in contact, a static equilibrium follows in which a surplus of negative charges will accumulate in the (thin) p region, and a surplus of positive charges will accumulate in the (much thicker) n region. These two layers produce an electric field similar to that of a capacitor with infinite parallel plates. In equilibrium, the total number of positive charges in the n region is equal to the number of…arrow_forwardmodels Diodes-Piece-wise Problem #1 In the circuit shown below, the voltage source Vin is given by the sketch.
