Abstract:The understanding and control of molecule-metal interfaces is critical to the performance of molecular electronics and photovoltaics devices. We present a study of the interface between C and W, which is a carbide-forming transition metal. The complex solid-state reaction at the interface can be exploited to adjust the electronic properties of the molecule layer. Scanning tunneling microscopy/spectroscopy measurements demonstrate the progression of this reaction from wide band gap (>2.5 eV) to metallic molecul… Show more
“… 68 In the reaction between the surfaces of C 60 and tungsten (W), the bond gap can be controlled by selecting the annealing temperature. 69 These are just some example of the bond gap engineering. A selective substrate for adsorption of gases or vapors can be achieved by bond gap engineering in gas adsorbents combined with modified fullerene.…”
Combinations of C60 and metal oxides (MOx) are interesting, not only because they display the individual properties of C60 and of MOx nanoparticles, but they may also exhibit synergetic properties that are advantageous for gas sensing applications.
