Nanotube Photoconductors
Abstract:
In the drive to shrink circuitry to nanometer dimensions, researchers have studied various strategies for making molecule-based photodetectors and other light-sensing devices. Typically, the electron-donor and electron-acceptor molecular components of the would-be devices form stacks of charge-transfer complexes when brought together. In such assemblies, charge carriers (electrons and holes) generally recombine too quickly to sustain a current.
