Abstract/OtherAbstract:
This article provides experimental evidence of one-dimensional (1D) behavior of silicon (Si) nanowires (NWs) at low-temperature through both, transfer (Id-VG) and capacitance-voltage (CV) characteristics. For the first time, operation of Si NWs in the quantum capacitance limit (QCL) is experimentally demonstrated and quantitatively analyzed. This is of relevance since working in the QCL may allow, e.g., tunneling field-effect transistors (TFETs) to achieve higher on-currents (Ion) and larger ON/OFF current ratios (Ion/Ioff), thus addressing one of the most severe limitations of TFETs. Comparison of the experimental data with simulations finds excellent agreement using a simple capacitor model.
