Organic Electronic Devices and Their Functional Interfaces
TL;DR: A comprehensive understanding of phenomena at interfaces with organic materials will improve the rational design of highly functional organic electronic devices.
Journal ArticleDOI
Charge-transfer excitons at organic semiconductor surfaces and interfaces.
TL;DR: Hot CT exciton states must be involved in charge separation in organic heterojunction solar cells because hot CT excitons are more weakly bound by the Coulomb potential and more easily dissociated.

Theory of Surface States
TL;DR: In this paper, it was shown that virtual or resonance surface states can exist which behave for practical purposes in the same way as the tails of the metal wave functions rather than separate states.
