In this talk, novel laser-based strategies will be introduced for controlled synthesis and fabrication of carbon nanotubes (CNTs) and CNT-based devices. CNTs are fascinating materials with extraordinary optical and electrical properties that make them potential candidates for a number of applications. However, integration of CNTs into functional devices is a great challenge in conventional CNT growth techniques. Additionally, applications of CNTs in electronic and optoelectronic devices are limited by variations in their structures and hence electronic properties. This talk will be mainly focused on self-integration of CNTs into functional devices via interaction of a laser beam with plasmonic nanoantennas to manipulate light at nanoscale for selective growth of CNTs in desired locations. Fabrication of plasmonic-enhanced infrared bolometers will be introduced using CNT-integrated nanoantenna arrays. I will then present laser-based methods to selectively remove metallic-CNTs from the CNT mixtures and modulate the electronic and optical properties of semiconductive-CNTs. Finally, silicon coating on the surface of CNTs in a laser-assisted gas-free process will be discussed.
