Q3) (i) Calculate the electrical conductivity of a piece of pure Si if it is given the number of intrinsic carriers at 300 K is 1 x 1010 cm3 and that the electron and hole mobilities are He = 1350 cm?.V-1.s1 = 450 cm?.V-1.s1 respectively. and Answer: 0.00000288JUnits(2.cm)1 (ii) Compare the conductivities between Si and Cu at 300 K as calculated from Q2 and Q3(i). Answer: Q4) Following on from Q3, the temperature now increases to 350 K. Describe semi-quantitatively how and why the carrier concentration and the conductivity will change due to this temperature change for both these two materials (Si and Cu). Answer:
