Figure 4From: Enhancement in electron transport and light emission efficiency of a Si nanocrystal light-emitting diode by a SiCN/SiC superlattice structureA schematic band diagram of the Si NC LED with 5.5 periods of SiCN/SiC SLs. A dotted oval in the upper part shows a specific conduction band diagram at the interface between SiCN and SiC layers in the SLs showing the formation of 2-DEG.Back to article page
