摘要：

A method is developed for eliminating spurious solutions from eight-band k.p theory. It reduces the bulk dispersion to a cubic equation (quadratic along [001] and [111]), yet gives results virtually indistinguishable from ordinary k.p theory. A unique operator ordering is established for heterostructures, and example calculations on superlattices show good results.
