How do Dirac materials differ from other materials?
Dirac materials are distinct from other materials due to their unique electronic properties, which are characterized by the presence of Dirac cones. These cones are a type of electronic dispersion relation that is linear in momentum, resulting in unique properties such as high carrier mobility and zero effective mass. This is in contrast to traditional materials, which have a parabolic dispersion relation and a non-zero effective mass. The Dirac cone structure gives Dirac materials their exceptional electrical and optical properties, making them promising for a wide range of applications. Additionally, Dirac materials can exhibit other unique properties, such as topological protection and quantum Hall effects.
The unique properties of Dirac materials are a result of their underlying electronic structure, which is different from that of traditional materials. In Dirac materials, the electrons behave like massless fermions, which gives them high mobility and makes them sensitive to external perturbations. This sensitivity can be exploited to create devices with unique properties, such as ultra-fast transistors and sensitive sensors.
