The article presents a study which demonstrates the magnesium diboride (MgB2) superconducting whiskers synthesized by hybrid physical-chemical vapor deposition (HPCVD). The HPCVD setups that were employed in this experiment were quartz chamber with induction heating and stainless steel chamber with resistivity heating. A scanning electron microscope was used to analyze the morphologies of the whiskers. It has observed an onset temperature of 39 K.

In this work, MgB(2) whiskers were fabricated on a copper substrate by using the hybrid physical-chemical vapor deposition, which was one of the most effective ways to make high quality pure MgB(2) films, with the possible growth mechanism discussed. The whiskers are hexagonal and conelike and grow along the [0001] direction with a single-crystal structure. The onset transition temperature is approximately 39 K, which is among the best in the published nanostructure MgB(2) papers. Fabrication of nanoscale MgB(2) whiskers provides the fundamental understanding of the effect of dimensionality and size on superconductivity.
