A method of X-ray characterization includes cooling a sample by delivering liquid nitrogen via a pipe to a sample stage of the X-ray diffractometer. The liquid nitrogen is discharged from the pipe to form a coolant stream. The pipe has an outlet to orient a flow of the coolant stream at the sample on the sample stage. The sample includes a substrate and a thin film formed on the substrate. During the cooling, diffraction data of the thin film and diffraction data of the substrate are collected by a detector of the X-ray diffractometer. A temperature of the thin film is determined based on the diffraction data of the substrate and thermal behavior of the substrate as a function of temperature. The thermal behavior of the substrate includes thermal expansion, thermal contraction or both.
