Abstract

CdSe nanoparticles (NPs) have shown superior photoconductivity as the particle size is shrunk to nano-scale. This provides a potential application as a nano-photo-sensor. In this work, we choose the CdSe NPs with diameter of 25 nm, which is comparable to the electron mean free path in bulk material, to get a high mobility in NPs. By using the DNA oligonucleotides as linkers through Au-S bonds, a new photo-sensing nano-device structure is proposed with Au NPs of 60 nm in diameter and CdSe NPs on a silicon substrate, where the CMOS interface circuits are designed to read signals of the sensor.
