Abstract : A method is given for calculating the deformation potential constants for materials with the diamond and zincblende structure by using the general framework of the pseudopotential approximation. The report includes a general discussion of deformation potential constants and the pseudopotential technique. A simple method of including the effects of spinorbit splitting in the pseudopotential formalism is considered in some detail, as is the strain variation of the kinetic energy, pseudopotential, and spinorbit terms of the Hamiltonian. The definition of the strain variation of these terms enables one to calculate the change in energy of an arbitrary electronic state due to a general strain. (Author)
