We develop (opto)electronic devices in atomically-thin materials such as graphene and transition metal dichalcogenides, complex oxides, topological insulators, and their heterostructures. We also study non-traditional transport phenomena such as electron-plasma waves and resonant-tunneling, and harness these into device applications. We also develop methods for the design of novel optical components and devices enabling extreme performance. Our main research interest is on the terahertz and far-infrared regions of the spectrum, but we are also interested in exploring materials and devices at RF, mid-IR, and UV frequencies.
- Implantable sensors and systems
- Neural interfaces, materials and technologies
- Harsh Environment MEMS, including:
- materials (SiC (on Si), SOI, GaN)
- metallisation systems for high temperatures and aggressive ambient conditions
- silicon fusion bonding and packaging issues
Our areas of study include non-volatile memory devices, microfluidics, microwave technologies for nanometrology, MEMS and NEMS, molecular electronics, and novel electronic materials (carbon nanotubes, and nano-particles) and devices.
We are looking towards the future of electronics by developing self-assembly and self-repairing circuits, non-destructive testing techniques, and new nanometrology tools for the evaluation and testing of these systems.
Yoon’s Research Group investigates the local properties of micro/nano structured systems at the length scales of relevant physical processes. Based on this fundamental knowledge, we develop exploratory devices in energy, optoelectronics, and chemical and biomedical applications. Our current research focuses on the development of in-situ, local measurement techniques using an electron beam and a focused light source. The versatile multi-probe approaches will elucidate structure-property relationship of a wide range of micro/nanomaterials and devices.
