Self assembled Cu3Si nanoislands and nanowires on Si(110) were fabricated with electron beam evaporation in ultra high vacuum while annealing the substrate at 600 ° C. Scanning tunneling microscopy technique was used to study the resultant nanostructures of sub 10 nm size. Surface images of a nanoisland and nanowire were obtained. The former showed evidence of single crystalline structures. The length,...
The Young-Laplace equation was incorporated into Timoshenko beam theory to model the free vibration of bending nanowires while taking into account the surface properties. Three boundary conditions were considered: cantilever, simply-supported and fixed-fixed ends. A method based on Fourier series expansion is introduced to solve for the free vibration solution with specific initial conditions. The...
This paper presents material properties of self-assembled Cu nanowires that were fabricated in the vacuum e-beam evaporation method. Diffraction patterns obtained from the Transmission Electron Microscopy (TEM) indicate that the Cu nanowires have two slightly different properties: single crystalline structures and polycrystalline structures with low angle grain boundary. Focused ion beam (FIB) was...
This paper describes an experimental procedure for growing self assembled Cu nanowires on a 4° miscut Si(001) substrate with and without the native oxide layer by the e-beam evaporation method. The physical characteristics of the Cu nanowires were observed using an in situ and ex situ scanning electron microscope (SEM). The results are compared with Ag nanowires that were fabricated with the same...
