We examine carbon nanotube (CNT) based hybrid systems by optoelectronic transport spectroscopy. CNTs are functionalized on-chip both with the "photosystem I" (PSI) and CdTe nanocrystals according to different chemical routes. PSI is a protein complex located in the thylacoid membrane of plants, algae and cyanobacteria which mediates the light-induced electron transfer in the photosynthetic pathway. The efficient energy conversion in the PSI and the adjustable optical properties of colloidal semiconductor nanocrystals, together with a nano-sized dimension, make both systems to promising candidates for applications in nano-optoelectronic devices. We will discuss the optoelectronic properties of PSI-CNT and CdTe-CNT hybrids.
