Double gated silicon nanowires are promising candidates for sensing purposes. In this work DG-SiNWs were studied both experimentally and by simulations. Our results confirm that the top-gate could indeed be used to tune charge distribution along the wire even in relatively narrow ~10 nm diameter nanowires. This property could potentially be used to enhance the sensitivity and the dynamic range of nanowire based bio and chemical sensors.
