WebJun 4, 1998 · Optical properties Thin films Form birefringence ABSTRACT Vacuum‐deposited thin films have a columnar structure that includes appreciable void volume. This structure is responsible for many differences between the properties of materials in the form of thin films and in bulk. WebThin film optical constants (i.e., optical bandgap, refractive index, and extinction coefficient) do exhibit thickness dependence [77,78], and hence finite size effects must be taken into consideration while comparing optical constants of ALD films with the bulk values.
