Carbon/Silicon Nanomaterials and Devices

Carbon/Silicon Nanomaterials and Devices

Carbon/Silicon nanomaterials and devices are promising for applications in many fields, such as solar cells, nanoscale electronic devices, light-emitting nano devices, laser technology, waveguide, chemical and biosensors, and catalysis. Our main research interests are listed as follows:

1. Controllable syntheses of semiconductor nanomaterials and development of functional nanomaterials and nanostructures

The target materials include silicon nanostructures (Si nanowires, Si quantum dots), carbon nanostructures (carbon nanotubes, carbon quantum dots, graphene, etc.), organic/inorganic hybrid nanomaterials, and functional nanomaterials with unique properties.

2. Chemical sensors

Nano chemical sensors are very useful in the applications of safety, health, hygiene, and anti-terrorism due to the specific interactions between nanomaterials and analytes, allowing tracking and detection of trace targets.

3. Nano catalysts and electrocatalysis

Owing to their special lattice structures and surface properties, nanomaterials show stronger catalytic capability and higher selectivity than traditional catalysts, and have become potentially useful catalytic materials in chemical industries.

4. Nano optoelectronic sensors and photovoltaic devices

Nano optoelectronic devices based on low dimensional nanostructures can overcome the limitations of traditional devices, and show a high degree of integration. The integration of nano optical and electronics devices with different functionalities can enhance the device performance significantly.

5. Nano-fabrication, micro/nano-processing technology

Nano-fabrication, and micro/nano-processing technology are the basis of the applications of nanotechnology. Our goal is to establish the basic theory in nano-fabrication, create new fabrication methodologies based on principles of physics, chemistry, and biology, as well as enhance the relationship between device performance and device structure.

6. Energy storage

Nanostructured materials have large surface areas and small dimensions. These structural features enable fast ion diffusion and charge transfer reaction on their surfaces, which are not possible with their bulk counterparts. They are promising materials for energy storage such as supercapacitors, lithium ion batteries and sodium ion batteries. 

7. Synchrotron radiation research

We provide a multi-disciplinary platform for materials study with novel synchrotron radiation techniques. The research directions include, but are not limited to, synchrotron radiation studies in 1) nano-materials and devices; 2) energy and environment related materials and issues; 3) polymer and macromolecules; 4) biomedical research; 5) development of novel synchrotron applications and theory.
