Fabrication and Growth of 111 SiNWs for Mechanical Spin-Detection

Pardis Sahafi, Institute for Quantum Computing

In our group, vertical Si nanowires grown on a 111 surface are used for force detection in nanoscale NMR and ESR. These measurements require a very long (20 µm) and minimally tapered vertical Si nanowires, to be used as nano-mechanical oscillators with a high quality factor (Q ~ 10⁴). The wires need to be grown at the edge of the substrate in order to allow us to optically probe their mechanical oscillations. In this talk, we discuss the techniques used in preparing these Silicon nanowires and how the various difficulties in fabrication and growth were overcome.

If you are coming from the Laziridis Centre, take the 11:35am shuttle to RAC 1 and return on the 1:15pm shuttle. There will be a light lunch served.
