“…XPS investigation of the surfaces after deposition revealed a weak Cr [43][44][45]. Consequently, only the C 1 s peak could be used efficiently for analysis purpose, and it is shown in Figure 4. Figure 5 shows examples of the acquired TDTR curves before and after heat treatment, with corresponding measured TBCs, for a system where an Al layer was deposited after heat treatment (Cr/C) and a system where such a layer was unnecessary (Mo/C).…”

The Thermal Boundary Conductance (TBC) between thin films of Cr, Mo, Nb and W and diamond substrates has been measured using time domain thermoreflectance before and after a high-vacuum heat treatment at 800 o C for 2 h. While no signs of carbide formation could be detected in as-deposited layers by Scanning Transmission Electron Microscopy Energy Dispersive Xray spectroscopy (STEM-EDX) elemental analysis, the heat treatment led to partial (W, Mo) or full conversion (Cr, Nb) of the film into carbide. The measured TBC values on as-deposited samples of 315, 220, 220 and 205 MWm −2 K −1 measured for, respectively, the Cr, Mo, Nb and W samples, were found to not be significantly altered by the heat treatment.

Molecular materials built from coordination complexes exhibit properties that can be explained through intermolecular electronic interactions driven by the ligand moieties. The nature of the ligand in the precursor molecules governs the connectivity of the magnetic phases and the possibility of producing them by using a gas-phase process. Metallocenium, metal bisdithiolate materials, and solvated and solvent-free [M(tcne)2] (tcne=tetracyanoethylene) magnets illustrate such features.

“…Formation of Mo 0 and MoЈ suggested a possible involvement of Mo in organic compounds other than the Mo(V) complexes. For example, Mo involved in carbonyl groups may have such low binding energies, and in particular, a negative shift of the binding energy occurs when the carbonyl groups are partially replaced by nitrogen or phosphorus causing an increase of the electron density surrounding Mo (23)(24)(25). Further verification was not conducted because of the limited quantity of the interaction products.…”
