The cross‐ and in‐plane thermal conductivities of 20–140 nm graphite thin film grown by chemical vapor deposition on Ni (111) measured by time‐domain thermoreflectance are found to be <50% of the that of highly oriented pyrolytic graphite. The reduced thermal conductivity is attributed to a combination of grain boundaries, structural disorder, and size effects.
