From: Photodetecting properties of single CuO–ZnO core–shell nanowires with p–n radial heterojunction
(a) TEM image and (b) SAED pattern of a single CuO nanowire, (c) TEM image and (d) SAED pattern of a single CuO–ZnO_2 core–shell nanowire, (e–l) EDX elemental mapping of a single CuO–ZnO core–shell nanowires and of the Cu, Zn and O as individual elements for (e–h) CuO–ZnO_1 and (i–l) CuO–ZnO_2.
