A new type of superlattice which is constructed with a periodic modulation of effective mass is proposed. Candidate materials for this superlattice are presented. The analysis shows that there exist continuously electronic subbands in real space.

The effective-mass theory or approximation (EMA), also termed the envelope function approximation, is widely used for calculating the electronic properties of carriers in potentials in an otherwise periodic crystal. The strength of the method is that the complexities of the periodic potential are hidden in the effective-mass tensor m∗ ij .

The modal effective mass is a modal dynamic property of a structure associated with the modal characteristics; natural frequencies, mode shapes, generalised masses, and participation factors. The modal effective mass is a measure to classify the importance of a mode shape when a structure is excited by base acceleration (enforced acceleration).

For analytical and some preparative columns in liquid chromatography, mass transfer resistance is usually negligible and the equilibrium theory suffices [7]. But for preparative columns with smaller plate numbers and large-scale columns, mass transfer effects are often significant and cannot usually be neglected.
