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 A Level Physics Tuition lessons. Do contact us to find out more!
