Professor Zikang Tang earned his BSc degree (1983) from Hangzhou University. He completed his PhD degree at Tohoku University in 1992. He joined the Physics Department of HKUST in 1994.
Professor Tang's main research interests include fabrication and characterization of nanostructured semiconductors and metals; study of light absorption and light emission of nanostructured materials.
Professor Tang and colleagues have demonstrated for the first time that single-walled carbon nanotubes with a diameter of 0.4 nanometer, the smallest carbon nanotubes in the world, are stable in air. They have not only provided novel samples for forefront research on carbon nanotubes, but have also opened up new fields for carbon tube applications in various hi-tech areas such as electronics, information technology and biology. Nature, a leading international science journal, published their research in November 2000. Following this success, superconductivity has been discovered in these nanotubes.
