Danish people have a relatively high death-rate, compared to other Nordic countries. This has not gone unnoticed. The government has been actively promoting a healthy lifestyle for quite some time now. This promotion is mainly focussed on physical health. With this public condenser project, an architectural interpretation of this healthy lifestyle is provided. Hereby, the focus is not just on physical health. Since mental health and physical health are always connected, the project addresses both subjects. On top of that, a healthcare component is also addressed within the intervention, in order to make sure that nothing is “broken”, and that the physical and mental health can be continuously developed. By taking a very contextual approach to the way that the design is created and structured, it is possible to strengthen the positive qualities of the site, whilst simultaneously tending to the aspects of the site that could be better. Therefore the project is not just conceptually integrated (by the overarching theme), but also contextually.

Difficulties in obtaining high-performance p-type transistors and gate insulator charge-trapping effects present two major challenges for III-V complementary metal-oxide semiconductor (CMOS) electronics. We report a p-GaAs nanowire metal-semiconductor field-effect transistor (MESFET) that eliminates the need for a gate insulator by exploiting the Schottky barrier at the metal-GaAs interface. Our device beats the best-performing p-GaSb nanowire metal-oxide-semiconductor field effect transistor (MOSFET), giving a typical subthreshold swing of 62 mV/dec, within 4% of the thermal limit, on-off ratio ∼10⁵, on-resistance ∼700 kω, contact resistance ∼30 kω, peak transconductance 1.2 μS/μm, and high-fidelity ac operation at frequencies up to 10 kHz. The device consists of a GaAs nanowire with an undoped core and heavily Be-doped shell. We carefully etch back the nanowire at the gate locations to obtain Schottky-barrier insulated gates while leaving the doped shell intact at the contacts to obtain low contact resistance. Our device opens a path to all-GaAs nanowire MESFET complementary circuits with simplified fabrication and improved performance.
