Crystallineamorphous coreshell silicon nanowires (SiNWs) grown separately on glass and stainless steel substrates were investigated by Raman spectroscopy. Raman spectra confirmed the presence of crystalline and amorphous silicon phases in both samples. With respect to bulk silicon, the crystalline Raman ...
We calculate the effects of phonon confinement on the Raman spectra of Silicon nanowires. The theoretical predictions are checked by measuring the Raman spectra of SiNWs selectively grown by plasma enhanced chemical vapor deposition (PECVD) employing gold as a catalyst. In order to fully account for...

cantilever. A deflection voltage of, for example, 0.5 V induces a 22.5 nm height difference, corresponding to a downward deflection of 45 nm at the end of the cantilever. Resonant Raman spectroscopy measurements were done while the AFM tip was pushing on the silicon cantilever. Each time the ...
Facile synthesis of highly uniform Mn/Co-codoped ZnO nanowires: optical, electrical, and magnetic properties. In this article, Co/Mn-codoped ZnO nanowires (NWs) were successfully synthesized on a silicon substrate by the thermal evaporation method with Au catalyst... Huifeng,Li,Yunhua,... - ...

Nanowires (NWs) are filamentary crystals with diameters of tens of nanometers and lengths of few microns. Semiconductor NWs have recently attracted a great interest, because they are emerging as building blocks for novel nanoscale devices. Since physical properties are size dependent, NWs display nove...
Surface-enhanced Raman spectroscopy (SERS) significantly amplifies the Raman scattering of molecules, enhancing their signals by several orders of magnitude. This emergent SERS-based optical detection strategies have attracted enormous research potential. In the current global context, the prevalence of envi...
