Hybrid Semiconducting Polymer / Carbon Nanotube Superstructures for Optical, Electro-Optic, and Spintronic Applications
Abstract
This proposal targeted three specific objectives: (1) Engineering short wavelength infrared detection materials. We aimed to open and modulate the bandgaps of m-SWNTs using chiral, ionic semiconducting polymers that helically wrap the nanotube surface at constant morphology and rigorously fixed chirality. We have introduced novel bandgap by design approaches, that enable organic/nanomaterial hybrid compositions having unique detection capabilities of ~ 2-2.5 m, thereby providing selective detector and sensor elements that cannot be realized or replicated with established inorganic semiconductors. (2) Developing materials that enable active refractive index control. We exploit helically wrapped semiconducting polymer s-SWNT structures to realize new classes of processable materials that possess dramatically enhanced utility for all-optical signal processing, which enables information processing rates that are much faster than that currently realized using opto-electrical switching
