Abstract

An infrared photo-detector (IR-PD) using self-assembled organic crystalline arrays has been reported [1]. Since such structure was found to have an activation energy as large as 0.40 eV, Mid- to Near- Infrared light can be detected. In this paper, we report that an IR-PD based on a combination of organic crystal material and plasmonic nano-pillar structures could detect over 2.0-μm-long IR light, which cannot be detected by using metal/Si Schottky diodes.
