PL,EL,light output powers,and WPEs. (a) PL spectrum taken from the Si NCs in the SiNx. The main peak position was around 680 nm. (b) EL spectra taken from the Si NC LED with 5.5 periods of SiCN/SiC SLs. The main peak position was around 680 nm. (c) Light output powers of Si NC LEDs with and without 5.5 periods of SiCN/SiC SLs, respectively. (d) WPEs of Si NC LEDs with and without 5.5 periods of SiCN/SiC SLs, respectively.
