(a) In-plane (left) and out-of-plane (right panel) EBSD data of domain structure-controlled Bi2Te3 films. The blue and green areas in the in-plane EBSD images represent each domain with a 60° rotation along the c-axis. Their interface is the 60° twin boundary. Blue, green and red colours indicate the crystallographic orientations of [210], [120] and [001], respectively. The detailed colour orientation code is shown in Supplementary Fig. 3. Scale bar, 10 μm. (b) The carrier concentration and (c) mobility as a function of the normalized boundary length. The error bars are estimated by the measurements of three samples for each data point.
