Taking into account the quantum size effects and considering three types of scattering from bulk impurities,rough surface and rough interfaces,we use the quantum-statistical Green's function approach to calculate the conductivity in multilayered cylindrical wire.It is found that in the lowest-order approximation of impurities,surface and interfaces scattering,the total conductivity is given by a sum of conductivities of all the subbands; and the scattering rates for the individual subbands due to the impurities,surface and interfaces are additive.
