1. Charge Separation on Localized Surface Plasmon and Hot Carrier Transfer to Semiconductors
Abstract : The relatively recent discovery that plasmonic nanoparticles generate energetic electron-hole pairs known as hot carriers has been the source of interest from many scientific groups. The capability to extract these short-lived hot carriers from metal nanoparticles (NPs) might potentially lead to applications in solar cells, photodetection, and photocatalysis. READ MORE

2. Studies of Charge Transport and Energy Level in Solar Cells Based on Polymer/Fullerene Bulk Heterojunction
Abstract : π-Conjugated polymers have attracted considerable attention since they are potential candidates for various opto-electronic devices such as solar cells, light emitting iodes, photodiodes, and transistors. Electronic de vices based on conjugated polymers can be easily processed at low temperature using inexpensive technologies. READ MORE

4. Nanoparticle plasmon influence on the charge carrier generation in solar cells
Abstract : Global warming is a potential threat to life on earth and to human society. It is by much evidence linked to the extensive use of fossil fuels in our present energy system. Replacing the fossil fuels by alternative sources of energy poses a tremendous challenge for mankind, but is not at all undoable. READ MORE

5. High-speed optical modulators based on intersubband transitions
Abstract : Optical modulators are essential components in high speedoptical communication. They are employed to circumvent theinherent speed limitations of direct modulated semiconductorlasers, and may also extend the transmission distance onoptical fibers by providing optical pulses with lowerchirp.
