Synthesis of MgB₂ nanowires and doped orthorhombic boron nanorods Available to Purchase

Chemical vapor deposition processes to create magnesium diboride (MgB₂) nanowires, a well-known superconductor, and orthorhombic boron nanorods are reported. These boron nanorods are doped with magnesium and sulfur, and the doping induces a number of defects in the material. The synthesis technique used to create these materials is based on a method used originally to create a variety of pure boron nanomaterials. The addition of sulfur and ammonia dramatically alters the process, resulting in new products. The morphology of these materials was characterized with scanning and transmission electron microscopy. Electron energy loss spectroscopy, electron diffraction and Fourier transform analysis were performed to determine crystal spacings and chemical composition of both materials. MgB₂ nanowires especially, because of their superconducting nature and small dimensions, have a number of interesting uses. This article contains supporting information that available online.
