Giving nanowires a DNA-like twist


Scientists have discovered a DNA-like twisted crystal structure created with a germanium sulfide nanowire, also known as a 'van der Waals material.' Researchers can tailor these nanowires in many different ways -- twist periods from two to twenty micrometers, lengths up to hundreds of micrometers, and radial dimensions from several hundred nanometers to about ten micrometers. By this means, they can adjust the electrical and optical properties to optimize performance for different applications.
