Recent advances in spin transport in organic semiconductors

Abstract

The spin relaxation time is long in organic semiconductors because of the weak spin-orbit and hyperfine interactions, leading to intensive study on spin transport in organic semiconductors. The rapid progress towards utilizing spin degree of freedom in organic electronic devices is occurring. While the spin injection, transport and detection in organic semiconductors are demonstrated, the fundamental physics of these phenomena remains unclear. This paper highlights recent progress that has been made, focusing primarily on present experimental work.
