摘要：

We present a general theory of compounds with partial long-range order. We derive a simple formula that determines the properties of a partially ordered compound from those of the perfectly random alloy and the fully ordered compound. The formula makes accurate predictions of both formation energies and electronic band structures. We also use the formula to predict the band gaps of Al1-xGaxAs/GaAs superlattices.
