Abstract:The discovery of new classes of materials with new functionalities or significantly improved performance has been a driving force in the advancement of modern science and technology, and in the improvement of our daily lives. We are now in an era of discovery of new materials, new physics, and new devices. This is the trend in the race represented by scientific research worldwide. This presentation will address the latest progress on the discovery of new class of advanced functional materials, and the discovery of their new phenomena and new devices. Novel approaches for designing new types of functional materials with novel electronic and multi-functional properties will be discussed. The presentation will be focused on materials with zero band gap, namely gapless semiconductors which have unique physical properties compared to conventional semiconductors, insulators and metals. An overview on novel physical properties will be given for some typical zero gap materials with either quadratic or linear dispersion. New physics and potential applications in spintronics, electronics, multiferroics on a number of spin related gapless semiconductors, topological insulators, and other new class of zero gap materials will be addressed. Some experimental data on their fascinating physical properties such as observation of Josephson supercurrent through a topological insulator surface state and room temperature giant magnetoresistance in topological Bi2Te3 nano-sheet will be presented.
