Critical Temperature Changes in Many-Layer Films between Plates

摘要

Two distinct mechanisms produce two separate terms in the change of the critical temperature Tc in an n-layer (n>>1) film. The interface interaction induces a change delta Tc, delta Tc/Tc < or = O(2/n). The finite thickness of a film gives another term in the change of Tc, which has the exponent 1/v approx. 1.56. Comparisons with experiments is made, and further experiments are discussed.
