Figure 2.

A low-magnification TEM image shows an individual Bi2Te3 nanowire with a diameter of 78 nm. A SAED pattern reveals that the Bi2Te3 nanowire is grown in [110] direction with high single-crystallinity. A high-resolution TEM image also indicates highly single-crystalline atomic arrangements without any defects.
