My main research achievements in the past five years have been the development of novel and special single crystal materials to support basic and applied research in solid-state physics, including large-scale type synchrotron radiation source and mid-word scattering, as well as micro-scale experiments such as STM and STEM. in the fundamental research of materials physics In this regard, important discoveries have been made about the changes in molecular bonding and physical properties caused by atomic defects. The main research directions and materials cover topological The magnetic and structure-related physical properties are discussed, such as edge bodies, topological semi-metals, thermoelectric materials, and superconductors. At the same time, through the natural treatment of the National Academy of Sciences, The integrated joint laboratory of cutting-edge crystal materials will
fully promote the basic and applied research of materials centered on new materials in Taiwan.

In Dr. Raman Sankar Laboratory, We study the fundamental properties of single crystals such as “Dirac Semi-metals, Surface Topological studies, Topological Insulators, Topological Crystalline Insulators, High Tc super conductors, Weyl Semi-metals, 2D materials, Thermoelectric materials, etc.,” 

New materials with exotic physical properties have always been the engine leading to a revolutionary development for human societyin history. In studying new materials of novel physical properties with application potential, the precisemechanism and physicalparameters must be thoroughly scrutinized using single-crystal samples, which has been demonstrated repeatedly in the development of thermoelectric materials, superconductors, and the latest topological materials. In particular, the research of topological materialsthat led to the 2016 Nobel prize in Physics had demonstrated an integrated and collaborated endeavor among theorists, experimentalists, and the crystal growers, especially when the theoretically predicted massless tunnelingbehavior via Dirac cones at specified k-pointsin the energy-momentum space must be verified by the Angle-Resolved Photon Emission Spectroscopy (ARPES) using single-crystal samples. While most experimental groups treated crystal growth as a secondary supporting technique, it is contradictory to find that all convincing experimental results rely heavily on single-crystal samples. A powerfulsingle crystal growth facility can support the materials researchcommunity in the traditional role and play the leadingrole once a new materialwith novel physicalproperties is confirmed through its single crystal form. The immediate goals for the new material development include room temperature high Tc superconductors, thermoelectric materials of high figure-of-merit ZT, battery electrodes of high capacity, and materials of high optical-electric conversion efficiency for the solar cell and artificial photosynthesis, just to name a few
