The researchers have been studying nonreciprocal ballistic transport in multi-layer Weyl semimetal films with surface engineering using the gauge-invariant theory. They found that the nonreciprocity comes almost entirely from the surface states while the bulk states barely have contribution.
Weyl semimetals are a type of material that has unique electronic properties, such as anisotropic weak ant right and anisotropic Fermi arcs. The researchers used the gauge-invariant theory to study the transport properties of these materials.
The study showed that increasing thickness of the Weyl semimetal film will suppress the nonreciprocal signal. This means that in order to observe significant non-reciprocal signals, the material needs to be very thin.
The researchers also found that the surface states play a crucial role in determining the transport properties of the material. The surface states are responsible for the non-reciprocal behavior and the bulk states barely have any contribution.
This study has important implications for the development of new electronic devices. For example, it could be used to create devices that can transmit information in one direction only, which is useful for secure communication.
