High-temperature heat treatment of a heat-resistant, condensation polymer poly ( ρ-phenylene-1,3,4-oxadiazole) yielded a large-area, flexible film composed of highly oriented and nearly ideal graphite crystallites. The graphitic behavior was exemplified by both the (002) lattice spacing of 3.354 Å and extremely small full width at half-maximum intensity of the (002) reflection, 0.16–0.17°, for the films heat treated above 2800 °C.

    Intercalation of aluminum atoms under a two-dimensional graphite film on a metal was studied by high-resolution Auger spectroscopy. The spectra were recorded directly from the highly heated (up to 2100 K) sample. It is shown that the efficiency of this process increases significantly if the film...

    The relationship between pulse accumulation and radial heat conduction in pump-probe transient thermoreflectance (TTR) is explored. The results illustrate how pulse accumulation allows TTR to probe two thermal length scales simultaneously. In addition, the conditions under which radial transport...
