"Our work is the first ab initio calculation of the key quantities of interest for hot carriers--lifetime, which tells us how long it takes to lose enera, and the mean free path, which tells us how far they travel before losing energy."
These electrons travel freely on average by a distance called electron mean free path equal to l = [[upsilon].sub.F][tau], where [[upsilon].sub.F] is the Fermi velocity.
Abstract: Polymers are usually considered thermal insulators, because the amorphous arrangement of the molecular chains reduces the mean free path of heat-conducting phonons.
