Hybrid Silicon Nitride Photonic Integrated Circuits Covered by Single-Walled Carbon Nanotube Films

Dynamic Thermal Control of Silicon Nitride Photonic Integrated Circuits

Multiple heaters in photonic integrated circuits must be controlled accurately to achieve reliable performance of the thermooptic system. In this paper, we show wavelength stabilization using a system with unique design for silicon nitride circuits. Keywords; Thermooptic, dynamic, control, feedback

Thermoelectric power of single-walled carbon nanotube films

We report measurements of the thermoelectric power ~TEP! S and electrical resistance R of thin films of tangled ropes of single-walled carbon nanotubes. Experiments at 300 K under applied force normal to the plane of the film revealed a ;10–20 % decrease in the four-probe resistance, indicating that the contact resistance between ropes had improved. The TEP, however, was not affected by the app...

Bolometric infrared photoresponse of suspended single-walled carbon nanotube films.

The photoresponse in the electrical conductivity of a single-walled carbon nanotube (SWNT) film is dramatically enhanced when the nanotube film is suspended in vacuum. We show here that the change in conductivity is bolometric (caused by heating of the SWNT network). Electron-phonon interactions lead to ultrafast relaxation of the photoexcited carriers, and the energy of the incident infrared (...

Aligned Growth of Single-Walled and Double- Walled Carbon Nanotube Films by Control of Catalyst Preparation

Integrated nanotube circuits: Controlled growth and ohmic contacting of single-walled carbon nanotubes

Single-walled carbon nanotubes are synthesized by chemical vapor deposition of methane at controlled locations on a substrate using patterned catalytic islands. The combined synthesis and microfabrication technique presented here allows a large number of ohmically contacted nanotube devices with controllable length to be placed on a single substrate. Transport studies demonstrate ohmic contacti...
