Figure 4From: One-dimensional CuO nanowire: synthesis, electrical, and optoelectronic devices applicationAtomic configurations and band structures of CuO NW with and without defects. (a) Ideal NW; (b) with a Cu vacancy; (c) with an O vacancy. Dark and light balls represent O and Cu atoms, respectively. Red/blue circles represent the band structures from electrons with spin up and down, respectively. The Fermi levels are shifted to zero.Back to article page
