Ramkrishna
Abstract
Topological insulators are a class of materials distinguished by their unique electronic properties arising from non-trivial topological order. This paper provides a comprehensive overview of topological insulators, starting with their theoretical foundations in condensed matter physics, including the basic concepts of topology and the emergence of topological phases. The classification and properties of topological insulators in different dimensions, along with notable examples such as HgTe and Bi2Se3, are discussed. Experimental methods for characterizing these materials and supporting evidence for their topological properties are reviewed. Furthermore, the paper explores the applications of topological insulators in electronics and spintronics, emphasizing their potential in quantum computing and spin-based devices. Current challenges and future directions in the field are also addressed, highlighting ongoing research efforts and emerging trends. Overall, this review underscores the significance of topological insulators in advancing both fundamental physics and technological innovation.
