Weyl Semimetals
Weyl semimetals are a class of materials that exhibit unique electronic properties due to the presence of Weyl fermions, which are massless particles that behave like chiral quasiparticles. These materials have a special band structure where conduction and valence bands touch at discrete points called Weyl nodes. This results in unusual phenomena such as high mobility of charge carriers and the potential for topological effects.
The unique characteristics of Weyl semimetals make them promising for applications in quantum computing and spintronics. Their ability to support surface states, known as Fermi arcs, allows for robust electronic transport, which can be harnessed in advanced electronic devices. Researchers are actively exploring these materials to unlock new technologies.
