Figure 5

Dark-field TEM images of (a) (c) luminous point A in diode #1CX and (b) (d) luminous point C in diode #1DX. The diffraction conditions for (a) (b) and (c) (d) were g = 0002 and g = \(11\overline{2}0\), respectively. The schematic on the right side of each figure indicates the layer structure.
