Anisotropic three-dimensional weak localization in ultrananocrystalline diamond films with nitrogen inclusions
L. H. Willems van Beveren, D. L. Creedon, N. Eikenberg +6
We present a study of the structural and electronic properties of ultra-nanocrystalline diamond films that were modified by adding nitrogen to the gas mixture during chemical vapou…
Observation of impedance oscillations in single walled carbon nanotube bundles excited by high frequency signals
George Chimowa, Siphephile Ncube, Somnath Bhattacharyya
We report experimental observation of impedance oscillations in single-walled carbon nanotubes measured from 100 MHz to 65 GHz on coplanar wave guides and a power law dependence of…
Conductivity crossover in nano-crystalline diamond films: Realization of a disordered superlattice-like structure
George Chimowa, Dimitry Churochkin, Somnath Bhattacharyya
We present the electrical transport characteristics of a batch of nano-crystalline diamond films of varying nitrogen concentrations and explain the conduction mechanism by the diso…
Origin of conductivity cross over in entangled multi-walled carbon nanotube network filled by iron
George Chimowa, Ella C. Linganiso, Dmitry Churochkin +2
A realistic transport model showing the interplay of the hopping transport between the outer shells of iron filled entangled multi-walled carbon nanotubes (MWNT) and the diffusive…
