Project Title

Plasmonically Enhanced Mid-infrared Narrow-bandgap Semiconductor Nanocrystals towards Practical Optoelectronic Applications

Award Citation

Working in the area of practical optoelectronic applications, Professor Rogach will explore the means and the mechanisms to enhance the performance of low-band-gap semiconductor nanocrystals with narrow inter-band or intra-band optical transitions lying in the near- and mid-infrared range, which he plans to achieve by interactions with plasmonic metal arrays. This research will offer significant improvements in the performance of infrared photodetectors and LED devices, and this in turn may lead to the practical realisation of those devices based on infrared semiconductor nanocrystals. The deliverables include material development and contributions to spectroscopic and conductivity studies for improving optoelectronic devices operating in the infrared.
