초록
CuInS2 (CIS) - ZnS core-shell quantum dots (QDs) were formed by a using sol-gel method, and nanocomposites consisting of CIS-ZnS core-shell QDs embedded in the poly(methymethacrylate) (PMMA) matrix were formed by a using spin-coating method. A absorption peak at 550 nm for the absorbance spectra corresponded to the optical excitation edge of the CIS-ZnS core-shell QDs. A peak at 700 nm for the PL spectrum was related to the recombination luminescence of the CIS-ZnS core-shell QDs. Capacitance-voltage curves for Al/CIS-ZnS QDs embedded in PMMA/p-Si device showed a hysteresis behavior with a flat band voltage shift.
