Highlight
Controlling the polarity in addition to the structural uniformity of ZnO nanowires is critical for real-world-device integration. We have recently demonstrated, by combining selective area growth with chemical bath deposition, the fabrication of epitaxial ZnO nanowire arrays with great structural uniformity and optical quality as well as with controllable polarity. These open new opportunities for fabricating complex heterostructures for electronic, optoelectronic and photovoltaic devices.
