摘要：

This letter reports the self-assembly and analysis of CdSe nanocrystal monolayers on both p- and a-doped GaAs substrates. The self-assembly was performed using a 1,6-hexanedithiol self-assembled monolayer (SAM) to link CdSe nanocrystals to GaAs substrates. Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), optical ellipsometry, photoluminescence (PL), and scanning tunneling microscopy (STM) measurements were used to confirm stable, disordered, densely packed CdSe nanocrystal monolayers separated from the substrate by a SAM of 1,6-hexanedithiol.
