“Plateau–Rayleigh” crystal growth is a technique that can be used to synthesize 1D materials. Here, periodic shells develop along a nanowire core to form nanostructures whose diameters can be modulated. A team of researchers at Harvard University has now extended this concept by making heterostructures in which one semiconductor (germanium or silicon) is deposited on a core of the other semiconductor to produce complex nanowire 1, 2 and 3D shapes. The materials created could be used in advanced electronics and optoelectronics devices……..
