Exfoliated graphene flakes at dielectric/organic semiconductor interface yield high-transconductance thin film transistors. Sevenfold increase in charge mobility was observed in poly(3-hexylthiophene) thin film transistors with graphene flakes. This effect is applicable to both, solution processed, and vacuum-evaporated organic transistors.

Spectroscopic ellipsometry combined with measurements of electrical characteristics and Kelvin probe force microscopy have been employed to investigate the interaction between graphene and a gold substrate, and the consequent changes of graphene's complex refractive index on gold. A strong blue shift, as much as 350 meV, of the prominent absorption peak of graphene has been observed,

We achieved 52% relative increase in efficiency of solar cells embedded with Mo6S9−xIx nanowires. The hole mobility was improved by a factor of 2.5. Polymer regioregularity has a large effect on Mo6S9−xIx containing solar cells’ performance. A small enhancement effect on light scattering by surface-coated Mo6S9−xIx nanowires was found.
