Abstract

The quantum confinement of Bloch waves is fundamentally different from the well-known quantum confinement of plane waves. Unlike that obtained in the latter are all stationary states only; in the former, there is always a new type of states -- the boundary dependent states. This distinction leads to interesting physics in low-dimensional systems.
