Materials engineering

We manipulate novel electronic materials with a particular emphasis on organic semiconductors. Emerging nanomaterials such as graphene, nanoparticles, proteins, as well as low-temperature processable oxides are also investigated as an enabler for new electronics platforms. As these materials often exhibit exotic structure-property relationships, we take a close look at their nanoscale organization, self-assembly, surface interaction, crystallinity, and doping mechanisms that underpin the behaviors of higher-level architecture.
Device manufacturing

Field-effect transistors, solar cells, memories, light-emitting diodes, and sensors are some of the representative devices that we fabricate and optimize. Our goal here is to diversify their physical form factors and electrical functionalities, to finally demonstrate well-defined prototypes that provide a potential use in wearable technologies, sustainable energies, flat-panel displays, and large-area flexible circuitries. A recent focus has been placed on the applicability of these building blocks to neuromorphic and bioelectronic systems.
Theoretical modeling

Unconventional devices based on new materials are often difficult to understand from a theoretical point of view. The problem is fundamentally associated with the impossibility of traditional semiconductor physics to fully account for new materials with complex chemical compositions and structural arrangements. To this end, we create numerical and analytical models that conceptualize critical phenomena prevailing in novel devices, in the hope that they may serve as an invaluable tool for robust parameterization and predictive simulation.
