Low-Resistance Electrical Contact to Carbon Nanotubes With Graphitic Interfacial Layer

On Contact Resistance of Carbon Nanotubes

Carbon nanotubes (CNTs) have found many potential applications stemming from their small dimensions and marvellous electronic, mechanical, and thermal properties. One of the barriers for using CNTs as building blocks in nanoelectronics is the high contact resistance. This paper reviews recent progress on the research of contact resistance of CNTs. It starts with a preview of two basic contact c...

Ohmic Contact with Enhanced Stability to Polycrystalline Silicon Carbide via Carbon Interfacial Layer

The development of electrical contacts to silicon carbide with low specific resistivity and stability is a critical requirement for harsh environment MEMS applications. In this paper, we present a novel method to lower the ohmic contact resistivity and enhance the stability of Pt contacts to polycrystalline 3C-SiC (poly-SiC) operated at elevated temperatures. In particular, nanocrystalline grap...

The role of electrical and thermal contact resistance for Joule breakdown of single-wall carbon nanotubes.

Several data sets for the electrical breakdown in air of single-wall carbon nanotubes (SWNTs) on insulating substrates are collected and analyzed. A universal scaling of the Joule breakdown power with nanotube length is found, which appears to be independent of the substrate thermal properties of their thickness. This suggests that the thermal resistances at SWNT-insulator and at SWNT-electrode...

Electrical conductance of carbon nanotori in contact with single-wall carbon nanotubes

The realization of the potential of carbon nanotori as elements of nanoscale devices based on their recently predicted unusual properties requires a thorough understanding of contacting these nanostructures. We carried out a series of calculations of the electric conductance of carbon nanotori contacted by single-wall carbon nanotubes to shed light on the effects of the geometry as well as the ...
