D3 - Nanotechnology and Nanostructured
Materials for Electronics and Photonics
Electronic materials in the nanometer scale have very unique properties
which are particularly important for future high performance electronic
devices. In this project we aim to develop new nanosized materials and the
relevant processing technologies for data storage and optical applications.
We take advantage of the state-of-the-art ion-beam implantation and analysis
facilities at CUHK to modify materials in order to generate new nanosized
materials. In order to study the evolution of these materials under the
influence of heat energy or during a chemical reaction, we use scanning
probe techniques including atomic force microscopy (AFM) and scanning
tunneling microscopy (STM) to image the atoms or nanosized features on the
material surface.
Applications
- Nanosized materials: High density magnetic and ferroelectric recording
for nonvolatile memory, giant magneto-resistance, luminescent displays
- Nanometric processing and characterization technologies: synthesis of
novel functional materials, surface modification, real-time imaging of
atoms on surfaces
Features
- Ion-beam processing provides a non-equilibrium material synthesis
route through which naturally uncommon but highly functional material
phases can be created
- Some of these materials have extremely high magnetic / ferroelectric /
luminescence figures of merit
- Scanning probe technique offers ultra-high resolution on sub-atomic
scale
