Extracted text: A) Determine potential barrier, 1) If the resistivity of the P-type and N-type of a silicone diode are 82-cm and 52-cm respectively. 2) If the doping densities of both P-region and N-region are tripled. Given that 1.6 x 10-1°C, nF1.5 x 101/cm 4= 500 cm²V"'s", lh= 1300 cm²V's 'and VT = 0.026 V at 300 K°.
