Molecular doped organic semiconductor crystals for optoelectronic device applications

Abstract

For semiconductors, doping is an efficient approach to tune their energy bandgaps, charge transport, and optical properties which enable the improvement of corresponding performances and also the possibility of multifunction integration. Recently, significant advances have been achieved for molecular doped organic semiconductors, especially doped organic semiconductor single crystals (OSSCs) which have features of well-defined packing structure, long-range molecular orders, and low-density defects for fundamental studies and improved properties. In this review, we will give a summary of this exciting progress for molecular doped OSSCs from the aspects of selection criteria of molecular dopants, the general growth method, resulted in optoelectronic properties as well as their applications in optoelectronic devices. Finally, a brief conclusion is given with challenges and perspectives of molecular doped OSSCs in this field.
