A new method is proposed to calculate the configurational averaged Green's function for amorphous semiconductors. In contrast to earlier work based on pseudopotentials this method is within the framework of the KKR approach. It, therefore, can avoid the approximations for the potential average necessary in the pseudopotential scheme. Some general properties of the resulting spectral function and density of states are discussed.
