متن کاملNegative Differential Resistance in ZnO Nanowires Bridging Two Metallic Electrodes
The electrical transport through nanoscale contacts of ZnO nanowires bridging the interdigitated Au electrodes shows the negative differential resistance (NDR) effect. The NDR peaks strongly depend on the starting sweep voltage. The origin of NDR through nanoscale contacts between ZnO nanowires and metal electrodes is the electron charging and discharging of the parasitic capacitor due to the w...
متن کاملGiant piezoresistance effect in silicon nanowires.
The piezoresistance effect of silicon has been widely used in mechanical sensors2–4, and is now being actively explored in order to improve the performance of silicon transistors. In fact, strain engineering is now considered to be one of the most promising strategies for developing high-performance sub10-nm silicon devices. Interesting electromechanical properties have been observed in carbon ...
متن کاملArea Effect of Reflectance in Silicon Nanowires Grown by Electroless Etching
This paper shows that the reflectance in silicon nanowires (SiNWs) can be optimized as a function of the area of silicon substrate where the nanostructure growth. SiNWs were fabricated over four different areas of silicon substrates to study the size effects using electroless etching technique. Three different etching solution concentrations of silver nitrate (AgNO3) and hydroflu...
متن کاملMechanically Tunable Photonic Crystals
The next frontier in photonic crystal research may be to achieve dynamic tunability that allows real-time, on-demand control of the photonic band structure. Recently, researchers have been working on a new strategy for achieving this goal—by applying mechanical force. This approach can produce much greater tunability than is possible with electro-optic materials and may greatly expand the usefu...
