III-V/III-N materials and devices have been spotlighted due to their excellent electrical and photonic properties, including a high breakdown voltage and an unique bandgap (from infrared to deep UV). Therefore, they can be applied to practical applications such as solid-state photonic (e.g., photodiodes, light-emitting diodes, solar/photovoltaic cells) and electronic device (e.g., high electron mobility transistor, microwave power amplifiers, THz devices and non-volatile memories)

With the advent of the IoT era, people have a strong desire to always keep electronic devices in their bodies. Accordingly, various types of wearable modules (smart phones/watches) have been developed, but they still have a rigid and limited device form. Therefore, we will develop wearable electronic systems and electronic skins with the ultimate form factor (freely bent and stretched electronics). The type of electronic device is not restricted. Finally, the devices will be integrated into a monolithic system.

The developed electronic devices will be realized by structural innovations through bio-inspired and biomimetic technologies. They will eventually be attached to the living body, treating diseases or monitoring vital signs in real-time.

Property enhancements of electronic devices will come from new structures in the micro/nano-scale of various materials. Novel structure will be realized by various fabrication processes. For example, the fabrication process can be nanowire (NW) growth, nanoparticle (NP) synthesis, roll-to-roll (R2R), roll-to-plate (R2P) or light-material interaction.
