Scientific investigations carried out in our group can divided broadly in to 4 sections.

1. Carbon Nanoelectronics

Carbon nanomaterials, particularly carbon nanotubes and graphene, have caught the attention of many scientists because of their exceptional electrical and physical properties. Our lab investigates both the fundamental electrical transport properties and the applications of the novel carbon nanoelectronics, with particular focus on RF and terahertz frequency region


2. Nanophonics and Photovoltaics

Strong quantum confinement in nanomaterials leads to unique optical and optoelectrical properties absent from bulk. We are interested in exploring novel nanophotonic devices based on nanocrystals, carbon nanotubes, graphene, and semiconductor nanowires. Currently, we are exploring ultrasensitive carbon nanotube photodiode and high-efficiency photovoltaic devices by utilizing carrier multiplication process in nanomaterials. Our particular interest lies in probing the ultrafast photocarrier dynamics by using terahertz electrical measurement technique.


3. Nanoelectronic Sensors

Nanoelectronics have intrinsic advantages as chemical and biological sensors. Their reduced dimension yields higher surface/volume ratio; and their electronic performance can greatly exceed conventional silicon device. We are interested in developing nanoelectronic devices based on carbon nanotubes, graphene, and semiconductor nanowires, and exploring their sensing capability at DC, RF, and terahertz frequencies.


4. Nanomaterial Synthesis and Nanofabrication

Discovering new material is crucial for the development of nanoscience and nanotechnology. New nanomaterials and nanostructures can render novel material properties, leading to new device functionality. We are interested in the synthesis of nanomaterials through wet chemistry and chemical vapor deposition (CVD) methods. We are also interested in developing novel nanofabrication methods for electronic and photonic applications.
