What is the defining characteristic of a Weyl semimetal?
AnswerClick to flip back
A
The presence of Weyl nodes in the electronic band structure
💡 Explanation:
Weyl semimetals are characterized by the presence of Weyl nodes, which are points in the Brillouin zone where the conduction and valence bands touch and the energy dispersion is linear. This unique electronic structure gives rise to a number of interesting properties, including the possibility of superconductivity.
