1. (Prof. 2. Fabrication of four-probe electrodes With the nanowires grown and their lattice structure characterized, we have proceeded to make four-probe electrodes for electrical transport measurements. In contrast to many other groups who usually apply two-probe measurements, we have attempted to focus our efforts on four-probe measurements in order to obtain the intrinsic electronic properties of the nanowires, without them being complicated by the contact resistances between the electrodes and the nanowire.

However, film thinning makes the advantage of heavy doping gradually vanish. For 15 nm thick films, not only does AVr become reasonable but also the doping effect is irrelevant. In other words, an undoped and ultra-thin MOSFET is particularly resistant to short-channel effects. Major side benefits are the high carrier mobility and excellent subthreshold slope. The difficulty of controlling or tailoring the doping in thin films is naturally erased. There are additional solutions for further improvement of AVr which aim to preclude the fringing field penetration in the BOX and substrate.
