Nanoelectromechanical systems have been developed for ultra-high frequency oscillators because of their small size and excellent material properties. Using flexural modes and electrothermal features in nanowires for frequency tuning necessitates a sound modeling approach. The quasicontinuum method was developed to link atomistic models with the continuum finite element method in order to study the...
In this paper, we investigate the electrical and optical properties of novel InGaAs nanowire solar cells. Key features like high optical absorption and excellent charge carrier mobility make them an attractive candidate to established solar cell technologies. The aim of our study is gain a deeper understanding of the underlying physics involved and to identify the limiting factors in the device under...
As the diameter of semimetal nanowires decreases semimetal to semiconductor transition occurs as a consequence of quantum confinement. This enables the use of bandgap engineering to form a field-effect transistor near atomic dimensions and eliminates the need for doping in the transistor's source, channel, or drain for sub-5 nm transistors. The use of strain as a ‘technology booster’ in transistor...
The axial buckling and the transverse vibration of nanowires were studied theoretically. It is found that the symmetry breaking and resulting in additional elastic parameters are of vital importance on overall elasticity of nanowires. The negative surfaces stress would destabilize the nanowire system at certain dimension and that would lead to spontaneous structuring of nanowires at very small surface...
Top-down method was used to fabricate zinc oxide (ZnO) nano wire field effect transistor (NWFET) biosensor. The nanosensor was used to measure the electrical characteristics of lysozyme (LYSO) and bovine serum albumin (BSA) protein solutions in phosphate buffered saline (PBS). The LYSO and BSA proteins are oppositely charged at measurement pH of 7.4. Subthreshold voltage shift of 340 mV and 700 mV...
