title = "Boundary engineering for SINIS bolometers with integrated tunnel junction coolers",
abstract = "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 dominates heat flow at low temperatures in suspended nanostructures. This allows the control of cooling and heating properties through contact boundary engineering. A solution to fabrication issues in the structural release of tunnel junction coolers is demonstrated by replacing copper with gold as the normal metal nanowire. These gold structures show phonon cooling from 115 mK down to 70 mK.",
