Dirac semimetals are a class of materials that exhibit unique electronic properties due to the presence of Dirac points in their band structure. At these points, the conduction and valence bands touch, allowing electrons to behave as massless particles. This results in high mobility and unusual responses to external fields, making them interesting for applications in electronics and spintronics. These materials often feature a three-dimensional structure and can be characterized by their topological properties. Examples of Dirac semimetals include Cd3As2 and Na3Bi, which have garnered attention for their potential in quantum computing and advanced electronic devices.
