Measuring the Electric Field Dependence of Photocurrent Quantum Yield in Suspended Carbon Nanotube pn Junctions

Creator:

McCulley, Daniel R.

Abstract:

In nanoscale materials, the Coulombic interaction between electrons are stronger than in bulk materials. These stronger interactions, caused by confinement and reduced dielectric screening, have interesting consequences for light-matter interactions. In carbon nanotubes (CNTs), strong interactions can enhance the impact ionization process, and thus assist photocurrent generation in CNTs. Conversely,...
