Dr. Raphael Tsu, provided the basic theory of negative differential conductance applicable to the man-made Superlattice introduced by L. Esaki and R. Tsu 40 years ago. Two years later, he obtained the tunneling through the double barrier structure, the basic unit of the superlattice structure. These results formed the for-runner of today's Meta-Materials and Nano-electronics.

Professor Raphael Tsu (with Tsu replaced by Zhu in pinyin) is a world leader in the areas of quantum properties of materials and device physics. An acknowledged authority in these subjects Professor Tsu has published more than two hundred scholarly papers in scientific journals; an author of a book "Superlattice to Nanoelectronics" dealing with materials and devices of which he is a holder of many patents for his discoveries and inventions. The description of his research contributions with Dr. Leo Esaki while at the IBM, T.J. Watson Research Center in Yorktown Heights was presented to the White House by the US Army Research Office, The Superlattice Story, played an important role in the 90's towards the US National Nanoscience Initiative (NNI). Dr. Tsu is a Distinguished Professor of Electrical Engineering as well as Optical Science and Engineering at the University of North Carolina at Charlotte. He is a fellow of the American Physical Society and ex-member of International Advisory Board of the Microelectronic Journal, Elsevier; winner of an Outstanding Contribution Award - IBM 1975; Alexander von Humboldt Award - 1975; Co-winner Am. Phys. Soc. International New Materials Prize - 1985. He is a Fellow of the American Physical Society. He has a Google citation number of 15,000 with h-index of 50. He received the best paper award at the 6th ICNFA'15 In Barcelona, "Overcoming Losses in Metamaterials", for the discovery of energy stored within the Bohr orbit of H-Atom as a reactive energy transfer to the H-atom within the Bohr Orbit. Recently he received the Bank of America Arts and Science Award 2016.
