Description:

Interfacing semiconducting nanostructures with conducting or insulating substrates to attain a three-dimensional (3D) integrated platform is highly desirable for advanced nanoscale electronics and optoelectronics applications. As such, the assembly and synthesis of these nanostructures, which demonstrate multiple dimensionality, using a bottom-up approach would be useful.  In this example, 1D ZnO nanowires about 80nm in diameter grow vertically out of the junctions of 80nm thick ZnO nanowalls.
