A steady current of 400 µA flows through the plane electrode separated by a distance dof 0.5 cm when a voltage of 12 kV is applied. Determine Townsend's first ionization coefficient if a current of 80 A flows when the separation distance is reduced to 0.1 cm, and the field is kept constant at the previous value.

6) 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 a) calculate the electrical conductivity of the material at 20 and 100 °C and b) the band gap of this material. 30 ст 2 ст 1 cm
