Figure 3From: Evolution of morphology and microstructure of GaAs/GaSb nanowire heterostructures Structural and compositional details of the S1 segment. (a) A TEM image of the S1 segment from FigureĀ 2c. (b) A high-resolution TEM image clearly showing the WZ structure of the NW segment from (a). (c) The typical EDS linescan result along the radial direction, which indicates that the S1 segment is composed of pure GaAs.Back to article page
