Colloidal quantum dot based light emitting devices on silicon substrate

Light sources based on silicon have been the subject of interest for many years. Silicon would not only provide high volume manufacturing for commercialization but also allow complementary metal oxide semiconductor (CMOS) compatibility enabling integration of light sources within CMOS circuitry. Colloidal semiconductor nanocrystals have narrow emission spectra which makes them an excellent choice for active media in optoelectronic applications. Moreover, solution processability of colloidal quantum dots makes processing and integration on the silicon platform easier. This thesis discusses the design and fabrication of colloidal quantum dot based light-emitting devices using inorganic materials on a silicon platform for visible wavelengths. The results demonstrate the ability to integrate colloidal quantum dots on silicon which would allow the development of compact light sources for optical communication.
