Abstract

Vacuum ultraviolet irradiation is used as a tool to systematically study the morphology, growth, and performance of small-molecule organic field-effect transistors. The surface energy can be carefully and precisely tuned by varying the dose of irradiation, allowing for the systematic study of the growth of an emerging organic semiconductor. This technique helps to methodically control the morphology and performance of organic semiconductors.
