Thick adherent diamond films on AlN with low thermal barrier resistance
Soumen Mandal, Jerome Cuenca, Fabien Massabuau +9
Growth of 100 m thick diamond layer adherent on aluminium nitride is presented in this work. While thick films failed to adhere on untreated AlN films, hydrogen/nitrogen plas…
Superconducting boron doped nanocrystalline diamond on boron nitride ceramics
Soumen Mandal, Henry A. Bland, Jerome A. Cuenca +2
In this work we have demonstrated the growth of nanocrystalline diamond on boron nitride ceramic. We measured the zeta potential of the ceramics to select the diamond seeds. Diamon…
Battery-like Supercapacitors from Vertically Aligned Carbon Nanofibers Coated Diamond: Design and Demonstrator
Siyu Yu, Nianjun Yang, Michael Vogel +6
Battery-like supercapacitors feature high power and energy densities as well as long-term capacitance retention. The utilized capacitor electrodes are thus better to have large sur…
Can ultraprecision polishing techniques improve the coherence times of nitrogen-vacancy centers in diamond?
G. Braunbeck, S. Mandal, M. Touge +2
We investigate the correlation between surface roughness and corresponding times of nearsurface nitrogen-vacancy centers (~7 nm/ 5 keV implantation energy) in diamond. For th…
Redox agent enhanced chemical mechanical polishing of thin film diamond
Soumen Mandal, Evan L. H. Thomas, Laia Gines +4
The chemical nature of the chemical mechanical polishing of diamond has been examined by adding various redox agents to the alkaline SF1 polishing slurry. Three oxidizing agents na…
Surface zeta potential and diamond seeding on gallium nitride films
Soumen Mandal, Evan L. H. Thomas, Callum Middleton +9
Measurement of zeta potential of Ga and N-face gallium nitride has been carried out as function of pH. Both the faces show negative zeta potential in the pH range 5.5-9. The Ga fac…
