Polycrystalline Organic Semiconductors for Low-Power AI-Integrated Devices: Fabrication and Characterization
Keywords:
organic semiconductors, polycrystalline films, neuromorphic devices, edge computing, intelligent electronics, sensing systemsAbstract
Polycrystalline organic semiconductors constitute a promising class of functional materials, combining architectural flexibility, compatibility with low-temperature processing, and tunable electronic properties. Owing to their ability to form ordered morphologies with defined crystallinity, these materials can be seamlessly integrated into energy-efficient intelligent systems—such as neuromorphic components, sensing nodes, and photo-analytical elements. In the context of rapidly growing interest in edge computing and Internet-of-Things infrastructures, they offer advantages over silicon counterparts, including mechanical robustness, spectral sensitivity, and the capacity for on-site primary signal processing. This study reviews methods for producing polycrystalline films, examines how fabrication parameters influence morphological and electrical structure, and surveys quality-control techniques at both micro- and structural levels. Organic semiconductors thus fulfil a strategic role in the design of adaptive, miniaturized, and self-learning devices operating under unstable conditions, forming the basis for subsequent advances in intelligent organic electronics.
