Research output: Contribution to specialist publicationArticle


The development of the all-silicon optoelectronics technology that can enable the integration of traditional compound-semiconductor optical materials with standard CMOS processing is discussed. Silicon nanocrystals have several applications in modulators, optical amplifiers and light emitting diodes. It is suggested that an ideal device for the study of charging effects on the optical properties of silicon nanocrystals is a nanocrystal floating-gate transistor with a transparent gate contact. Observations confirm that charge injection into the array of nanocrystals can be used directly to modulate the photoluminescence output of the device enabling higher quantum efficiency.
