摘要：

A new concept for solving the set of coupled equations of a multicomponent envelope-function problem is presented which is based on a quadrature method for the integral equations in momentum space. It is applicable to quite general k . p Hamiltonians, considers the boundary conditions at interfaces in a natural way, and avoids automatically any spurious solutions. The flexibility and potential of the method are demonstrated by a few selected examples.
