Witryna14 cze 2024 · It is equal to the number of molecules reaching at the surface * surface area of the nucleus. Growth of nucleated sites and nano wire formation. ... Molecular volume of ZnO = 2.541 × 10 −29 m 3 /molecule. Impingement rate = 0.67 × 10 18 molecules/m 2 s. (which is calculated by multiplying the molecular volume with … Witrynameasured distribution of impinging gas molecules showed a strong position dependence. Indeed, a 300-lm shift of the deposition area to a position further away from the impingement center spot resulted in a 50 % decrease in the precursor impinging rate on the surface area. With the same parameters, the precursor distribution was …
