Magnetotransport measurements in large diameter multiwall carbon nanotubes (20–40 nm) demonstrate the competition of a magnetic-field dependent bandstructure and Altshuler–Aronov–Spivak oscillations. By means of an efficient capacitive coupling to a backga ...
Surface science and molecular biology are often concerned with systems governed by fluid dynamics at the nanoscale, where different physical behaviour is expected. With advances in nanofabrication techniques, the study of fluid dynamics around a nano-objec ...
Metals are known to exhibit mechanical behaviour at the nanoscale different to bulk samples. This transition typically initiates at the micrometre scale, yet existing techniques to produce micrometre-sized samples often introduce artefacts that can influen ...
This thesis describes the synthesis, characterisation and macroscopic manipulation of carbon nanotubes. Two interconnected aspects were investigated: (i) growth of carbon nanotubes by catalytic chemical vapour deposition of acetylene and (ii) assembly and ...
Multiwalled carbon nanotubes (MWCNTs) were grown by chemical vapor deposition by applying C2H2 fluxed over Fe1-xCox catalyst supported by alkaline earth carbonate. Detailed investigations of the chemical process occurring prior and during the growth allowe ...
We present local and non-local electron transport measurements on individual multi-wall nanotubes for bias voltages between 0 and about 4 V. Local current–voltage characteristics are quite linear. In contrast, non-local measurements are highly nonlinear; t ...
