Abstract

Conductive carbon nanowires were made on the polished surface of a single crystal CVD diamond by 30 keV Ga^+^ ion beam focused to 20 nm. Measurements of conductance of the as‐irradiated nanowires and those annealed at temperature 1400 Β°C revealed the onset of the ion‐induced conductance to be of 2 Γ— 10^15^ cm^–2^. Short nanowires (sub‐micron length) irradiated with subthreshold doses from 5 Γ— 10^14^ cm^–2^ to 3 Γ— 10^15^ cm^–2^ exhibited unusually high conductivity of 10^5^ Ξ©^–1^ cm^–1^ well exceeding the conductivity of bulk graphite and comparable with that of metals. Tentative explanation of the effect is formation of chains of highly conductive carbon nanorods along γ€ˆ100〉 direction in diamond lattice. (Β© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract Carbon nanodots were made on the polished surface of a single crystal CVD diamond by a focused 30 keV Ga^+^ ion beam. The electrical conductance via the nanodots was measured in two types of structures: single nanodots embedded in the gaps of broken carbon nanowires and linear chains of
