Focus on Silicon Nanowires: When is Ultrathin Too Thin

The electronic properties of silicon nanowires (SiNW) have led to their application in a variety of devices, such as chemical and biological sensors, field-effect transistors, lithium batteries and photovoltaic cells. Of late, recent work has been focused on scaling down the size of these devices, resulting in research on even smaller nanowires.
