Direct Growth of Highly Mismatched Type II ZnO/ZnSe Core/Shell Nanowire Arrays on Transparent Conducting Oxide Substrates for Solar Cell Applications

Abstract

Large-area, well-aligned ZnO/ZnSe core/shell nanowire arrays are synthesized directly on a transparent conducting oxide substrate. HRTEM reveals that ZnO and ZnSe have wurtzite and zinc blend crystal structures, respectively (see figure), the interface is smooth with no transitional layer, and ZnSe grows epitaxially on the ZnO core.
