Analytical Modeling of Unwanted Interstitial Growth in Silver Nanowire Production

Current methods of synthesizing silver nanowires on ferroelectric, periodically poled lithium niobate (PPLN) crystals are limited due to unwanted interstitial growth of silver between nanowires. It is believed that surface imperfections on the crystal wafer become sights of electric field abnormalities that cause the growth away from the180domain boundaries, the location of desired wire sites. An analytical model is prepared which investigates the electric field abnormalities created by screening charges both at topological deformities (i.e. scratches) and at the domain boundaries of the PPLN crystal. Results from the model are compared to results from colleagues using experimental and computational methods. The size and shape of the ferroelectric lithographic silver nanowires on PPLN make them appropriate for use as wires in integrated circuits or as surface enhanced Raman Spectroscopy substrates
