Rational design of gold micro- and nanowires for high spatial and temporal resolution thermal investigations

The development of the resistively heated nanoscale elements, such as metallic microwires and carbon nanotubes, has attracted much attention in various areas of science and technology. This area of research benefited from recent developments of new fabrication processes in nanotechnologies and is motivated by applications in microelectronics and sensors. In this presentation we focus on the thermal characterization of metallic micro- and nanowire heaters including both the spatial and the temporal response of nanowires, which we investigate both experimentally and using finite element simulations. These latter appear as a very useful tool for the design of on-chip nano-heaters.
