Coherent transport in carbon nanotubes

Abstract:

Carbon nanotubes are one-dimensional ballistic conductors with coherence lengths on the order of micrometers and sharp van Hove singularities in the density of states. Notwithstanding extensive theoretical and experimental work, there are still interesting open questions, including the role played by van Hove singularities in their electrical properties and how contact probes affect ballistic transport. I will summarize our recent measurements on different coherent phenomena, including non-local transport and possible occurrence of intrinsic superconductivity. I will also discuss how coherent transport in carbon nanotubes is affected by Van Hove singularities through the quantum capacitance
