Advances in morphology control of organic semiconductor enabled organic transistor-based chemical sensors

Abstract

Electronic sensors have achieved tremendous progress in research and industry fields, and organic transistors are being developed as potential candidates with high performance and low cost. Considering the carrier transport and signal transition occurring within the active layer in the transistor, controlling the molecular stacking and microstructure of organic semiconductor films becomes an attractive alternative for achieving high sensitivity and selectivity. In this review, we provide a brief overview of the fundamentals of organic transistor based chemical sensors, as well as the advantages and the mechanisms of morphology dependent sensing performance in organic transistors. In addition, we give an insight into the strategies developed to manipulate the film properties in chemical sensors. Further, we also discuss current challenges and opportunities in the morphology control of organic transistor-based sensors toward practical applications.
