Intrinsic Linear Dichroism of Organic Single Crystals toward High-Performance Polarization-Sensitive Photodetectors

Tianyu Wang et al.

Summary: This study demonstrated the construction of polarization-sensitive photodetectors based on the organic semiconductor 2,6-diphenyl anthracene (DPA) single crystals, showing strong anisotropy in molecular vibration, optical reflectance, and optical absorption. Theoretical calculations confirmed that the polarization sensitivity of DPA crystals originated from the anisotropic in-plane crystal structure. This work opens up possibilities for developing compact polarization photodetectors and new functionalities in flexible optical and optoelectronic applications.
