【 摘 要 】

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