Organic Semiconductors: Wide‐Range Refractive Index Control of Organic Semiconductor Films Toward Advanced Optical Design of Organic Optoelectronic Devices (Adv. Mater. 47/2012)

Abstract

Over the past quarter century of organic semiconductor research, refractive index control of organic semiconductor thin films has never been discussed. Daisuke Yokoyama and co‐workers demonstrate a large refractive index difference of 0.58 in organic semiconductor films and fabricated organic photoconductive DBRs (distributed Bragg reflectors) with a reflectivity of >98%. These findings provide us with new additional freedom and strategies in advanced optical design of organic semiconductor devices.
