Charge carrier mobility measurement in organic semiconductors

Sanjay Tiwari, Shikha Tiwari

Organic electronics and optoelectronics are newly emerging fields of science and technology that cover chemistry, physics, and materials science. Electronic and optoelectronic devices using organic materials are attractive because of the materials characteristics of light weight, potentially low cost, and capability of large-area, flexible device fabrication. Such devices as OLEDs, OPVs, and OFETs involve charge transport as a main process in their operation processes, and therefore, require high-performance charge-transportingmaterials. In this reviewarticle, first, some basic aspects of charge transport are discussed and then important mobility measurement techniques employed in electronic and optoelectronic devices such as OLEDs, OPVs, and OFETs are described.
