Abstract:

Nanoscopically engineered organic semiconducting materials have attracted great interest recently as they are promising building blocks for various electronic and optoelectronic applications. In addition, multicomponent semiconducting materials such as p-n junctions or core-shell structures are of great importance both in modern electronic applications and in understanding other semiconductor devices. They can potentially realize novel or improved chemical and physical properties that cannot be obtained from the single component system or their bulk materials. Furthermore, the physical structure of an organic solid is strongly affected by the surface of underlying substrate. Controlling this interface has always been an important issue to improve device performance in organic electronics. In this study, unconventional organic semiconducting nanomaterials including branched nanowires, nanoporous organic semiconducting films, and core-shell structured 1-D nanomaterials have been fabricated, and applied in high-performance flexible and wearable sensors such as photodetectors, chemical and biological sensors. In addition, the fundamental charge transport and photophysical phenomena of organic semiconducting nanomaterials have been investigated. Furthermore, an approach that utilizes an organic heterointerface to improve the crystallinity and control the morphology of organic thin film has been developed. Our approach opens a new way for the fabrication of nanostructured semiconducting layers towards high-performance organic electronics.
