The gravity effect on spin coating glucose thin film. Issue 1 (July 2016) - Han, P
Abstract: We demonstrate the gravity effect on spin-coated glucose film by comparing properties of films fabricated by two different methods: erected spin coating (ESC) and inverted spin coating (ISC). A "Bi-Layer" model, i.e. substrate effect layer and free layer, for spin coating is proposed to analyze the gravity effect on spin coating process which offers a more accurate prediction on film thickness. The thickness and deposition pattern are different in samples fabricated by ESC and ISC methods in titrating-repeated spin coating experiment. Finally, in a glucose coating/ferromagnetic composite structure, an enhanced Kerr rotation with the enhancement factor of 2.11 is achieved by ISC method.
