In microcalorimetry for measuring heats of adsorption on clean single-crystal
surfaces, a pulse of gas from a molecular beam adsorbs on an ultrathin
single crystal's surface, causing a measurable transient heat input
and temperature rise. One new and sensitive method of heat detection
uses a 9 um pyroelectric polymer ribbon, which is mechanically driven
to make a gentle mechanical/thermal contact to the back of the single-crystal
sample during measurement (J.T. Stuckless, N.A. Frei, C.T. Campbell,
A novel single-crystal adsorption calorimeter and additions for determining
metal adsorption and adhesion energies, Rev. Sci. Instr. 69, 1998,
2427�2438). Here we describe simulations of the signal pulse shape
and an analysis of absolute signal intensities, based on system parameters
such as the detector pyroelectric coefficient and thermal conductivities
of the detector and sample, in order to understand heat collection
efficiency in this and related calorimetric techniques.
