Hetero-integrated Nanostructures and Nanodevices

Heterogeneous Integration at the Atomic Scale

Combining chemical synthesis and physical assembly approaches, we are developing powerful strategies for the hetero-integration of multi-composition, multi-structure and multi-function at the nanoscale, and by doing so, creating a new generation of integrated materials and nanosystems with unprecedented performance or unique functions to break the boundaries of traditional technologies.

Atomically Thin Electronics and Photonics

Using two-dimensional layered materials and their heterostructures, we are pushing the electronic and photonic devices towards the ultimate limit of single atomic layer, creating a new generation of devices with unprecedented performance, unique functions and/or extraordinary flexibility.

Energy Harvesting, Conversion and Storage

Through rational design and nanoscale eintegration of highly distinct materials and functions (e.g., light harvesting, charge transport, or catalytic capabilities), we are creating new material systems for highly efficient energy harvesting, conversion and storage.

Biomedical Sensing and Therapeutics

With comparable size to functional biological building blocks, nanoscale systems are ideally suited for interfacing with biological systems. We are designing nanoscale electrical and optical systems that can greatly expand our capability in probing, imaging, monitoring, and manipulating biological processes with unprecedented resolution, sensitivity and precision.
