Abstract

In dealing with small particles it is often assumed that their lattice properties can be described by semiinfinite models. These and recent experimental results1 on the low-temperature specific heat of small metal particles from 1.5 to 15°K indicate that this approach is limited. The enhancements are not proportional to the surface area and are not quadratic in temperature as predicted by semiinfinite theories.2; A decrease in the enhancements at lowest temperatures agrees qualitatively with the effect of finite size, which places a lower limit on the frequency spectrum. We have also observed an anomalous behavior in the electronic specific heat which probably results from the boundary conditions on the electronic wave functions which affect the quasiparticle states.
