Electro-thermal aspects in carbon based interconnects

Verma R., Bhattacharya S., Mahapatra S., Indian Institute of Science, IN

The tremendous rise in Joule-heating in conventional ICs has led down ITRS to ensure on material alternatives that surpasses break-down current density and thermal conductivity (κ) beyond room temperature (RT). In recent years, suspended metallic [...]

Direct nanoscale imaging of ballistic and diffusive thermal transport in graphene nanostructures

Kolosov O.V., Pumarol M.E., Tovee P., Rosamond M.C., Petty M.C., Zeze D.A., Falko V., Lancaster University, UK

We report direct imaging of thermal transport in single and few-layer graphene with approximately 50 nm lateral resolution using high vacuum scanning thermal microscopy. Images reveal low thermal resistance of areas of suspended graphene where [...]

Heating double wall carbon nanotubes with UV photons

Puech P., Bassil A., Flahaut E., Bacsa W.S., University Paul Sabatier, FR

Light absorption leads inevitably to electronic excitation and inelastic electron scattering, creating phonons and resulting in the increase of the lattice temperature. By using photons with energies significantly above the fundamental band gap of the [...]
