WebThe electronic configuration of germanium is (Ar)(3d) 10 (4s) 2 (4p) 2 and the atomic radius is 0.137 nm. Germanium has the diamond cubic crystal structure shown, an fcc lattice with a basis of two germanium atoms, one at (0,0,0) and the other at (1/4, 1/4, 1/4) in units of the cube edge. It can also be visualized as two interpenetrating fcc ... WebAt temperatures near room temperature, the temperature dependence of the conductivity for intrinsic germanium is found to equal: o =C (T 2 )exp 2kT where C is a temperature-independent constant and T is in Kelvins. a) Calculate the intrinsic electrical conductivity of germanium at 150°C. b) Determine the temperature at which the electrical ...
