MoS2 nano-flakes on c-face sapphire substrate substrates.
(A) Typical AFM height images of MoS2 flakes grown on c-face sapphire substrates. Inset shows a non-continuous MoS2 layers formed in triangular feature; (B) AFM image of the corresponding regions after Au nano particles decoration. For these samples, the Au precursor adsorption time was 20 seconds and rinsed with DI water after dip casting; (C) photoluminescence spectra for the obtained CVD-MoS2 layers, inset shows the Raman spectra of the CVD-MoS2. Both Raman and PL experiments were performed using a confocal spectrometer with 476 nm excitation laser.
