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…
Superconducting nano-mechanical diamond resonators
Tobias Bautze, Soumen Mandal, Oliver A. Williams +3
In this work we present the fabrication and characterization of superconducting nano-mechanical resonators made from nanocrystalline boron doped diamond (BDD). The oscillators can…
The Diamond SQUID
Soumen Mandal, Tobias Bautze, Oliver A. Williams +7
Diamond is an electrical insulator in its natural form. However, when doped with boron above a critical level (~0.25 at.%) it can be rendered superconducting at low temperatures wi…
Nanostructures made from superconducting boron doped diamond
Soumen Mandal, Cécile Naud, Oliver A. Williams +6
We report on the transport properties of nanostructures made from boron-doped superconducting diamond. Starting from nanocrystalline superconducting boron-doped diamond thin films,…
