Device physics and spectroscopy techniques for organic/nano materials
Conjugated semiconducting organic materials and nano-materials have unique properties that can facilitate new applications in both electronics and biology. The high quantum efficiency of organic materials has already been applied in the area of organic-light-emitting diodes (OLEDs). Multi-exciton generation (MEG) due to quantum-size effect has also been demonstrated in quantum dots, which is believed can provide a more efficient photon-to-electron generation pathway for photovoltaic application. Having better understanding of the physics background of materials is certainly a gateway for developing new applications.
In this research project, our interest is investigating the photoelectric properties of organic/nano-materials. One of primary focus is on the charge transfer (CT) processes in these material systems. It is simply because CT process is the major mechanism to determine the performance of electronic devices. In this project, the candidate will build up knowledge of charge-carrier transport and charge transfer in organic / nano-materials. He/She will also design experiment and develop spectroscopy technique to investigate the physical process.
