We studied the phonon transport in free-standing 1 µm thick silicon-nitride membranes at temperatures around 100 mK. By varying the geometry of the membranes and the dimensions of the heater element, we are able to distinguish between radiative and diffuse phonon transport. The data indicate that the transport is radiative ballistic with a lower limit to a phonon mean-free path of about 1 mm and that the probability for specular reflection from the surface is at least 0.99. The tested silicon-nitride membranes were grown on Si(100), Si(110), and polycrystalline-Si and the transport properties show no dependency on the substrate

The performance of X-ray microcalorimeters with a Ti/Au Transition Edge Sensor (TES) and a Cu absorber has been investigated. With these microcalorimeters we achieve energy resolutions below 4.5 eV FWHM for 5.89 keV X-rays in combination with a response time of about 100 μs. The measured energy resolution is analyzed and discussed based on spectral and RMS noise measurements. Excess noise was present which, in one case, could be fitted by noise proportional to 1α, suggesting the presence of thermal fluctuations in the TES. Variation in geometry and illumination was examined but did not influence the energy resolution.

It has been recently demonstrated that superconducting transition edge-sensors behave as weak-links due to longitudinally induced superconductivity from the leads with higher
