A thin film is a layer of material ranging from fractions of a nano-meter to several micrometers in thickness. A familiar application of thin films is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. Thin film science involves concepts learnt at JC level, typically interference and diffraction principles.
More of its applications will be discussed at our Physics Tuition lessons. Do contact us to find out more!
