Thermal properties of materials

A small implanted monolithic silicon calorimeter has been bombarded with alphaparticles at low temperatures in order to determine its thermal properties. From the temperature dependence of the pulse height and the time structure, we have obtained values for the lattice contribution to the heat capacity in excellent agreement with theory, while the contributions from the implanted zone are about an order of magnitude larger than expected from data on diffusion-doped semiconductor. This and other thermal properties are discussed.
