By growing 2D nanosheets along the surface of a 1D nanowire, scientists have synthesized a new 3D nanoscale heterostructure that they call—for appropriate reasons—”shish kabobs.” Due to the integration of the two dimensionalities, the new structures could have a wide variety of applications, such as for solar energy conversion, energy storage, and photonics.
The scientists, Chun Li, et al., at North Carolina University in Raleigh, North Carolina; and Oak Ridge National Laboratory in Oak Ridge, Tennessee, have published a paper on the nanosheet-nanowire heterostructures in a recent issue of Nano Letters.
So far, most research on growing nanoscale heterostructures has focused on combining materials that have the same dimensions. Studies that involve combining materials with different dimensions have remained limited because it is much more difficult to integrate these materials into a single structure due to their different growth mechanisms.
