A new form of the Kronig-Penney model has been developed which is more general and practical than the new form in Ref. [1] . It gives not only odd and even index subbands separately but also wave functions for all k values. Moreover, a thorough analysis of the parity of tin-wave functions can also be given. Hence it affords a more suitable theoretical form for the analysis of superlattices and application to device designs.
