In this paper we report a study of the effect of vacuum annealing at 400°C on the properties of normal metal-insulator-superconductor (NIS) tunnel junctions, with manganese doped aluminium (Al:Mn) as the normal metal, aluminum as the superconductor

Phononic crystal (PnC) membranes are a promising solution to improve sensitivity of bolometric sensor devices operating at low temperatures. Previous work has concentrated only on tuning thermal conductance, but significant changes to the heat capaci

Thermomagnetic avalanches in superconducting films propagating extremely fast while forming unpredictable patterns, represent a serious threat for the performance of devices based on such materials. It is shown here that a normal-metal frame surround

In a previous publication [I. J. Maasilta, AIP Advances 1, 041704 (2011)], we discussed the formalism and some computational results for phononic thermal conduction in the suspended membrane geometry for radial heat flow from a central source, which

The responsivity and noise of a voltage-biased superconducting transition-edge sensor depends strongly on the details of its thermal model, and the simplest theory for TES response assumes a single heat capacity connected to the heat bath. Here, anal

We discuss computational analysis of phononic thermal conduction in the suspended membrane geometry, in the case where heat can flow out radially in two dimensions from a central source. As we are mostly interested in the low-temperature behavior whe

The feasibility of boundary engineering for the improvement of bolometric detectors and tunnel junction coolers is investigated. It can be shown, by comparing results of suspended and bulk tunnel junction coolers, that ballistic phonon transport domi

Measurement of the complex impedance of a bolometric detector has become a standard technique to determine the important thermal and electrical parameters of the device. We present here a new way to analyze the complex impedance data of a TES detecto

We have used normal metal-insulator-superconductor tunnel junctions as thermometers at sub-Kelvin temperatures to study the electron-phonon (e-p) interaction in thin Aluminum films doped with Manganese, as a function of Manganese concentration. Mn in
