Hetero-integrated Nanostructures and Nanodevices

FrontSlideshow

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.
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.

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.
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.

  • Using Electricity to Clean Silver Nanowires
    Jan 15, 2020

    Transparent electrical conductors are useful, e.g., in solar cells, sensors, displays, or smart windows. Indium tin oxide (ITO) thin films are commonly used for such applications, but the material is brittle and can crack under mechanical stress. Thin films made from silver nanowires are a possible alternative as a flexible, transparent conductor. However, their conductivity is reduced by polyvinylpyrrolidone (PVP) ligands that are used during nanowire synthesis and remain on the surface.
