Difference between si and ge material

Web1 Answer. At the interface between n-type Si and Ge, due to Fermi level pinning by interface states, usually an electron depletion zone and possibly a hole inversion layer forms with lateral thicknesses on the order of at least 10nm. Therefore, for a nanowire you cannot use the bulk material conductivities to calculate the resistance of the wire.
