Dirac metals

Researchers from IIT Bombay have discovered special properties in a class of materials called “semi-Dirac metals”- such materials would be transparent to light of a given frequency and polarisation when it is incident along a particular direction. The material would be opaque to the same light when it falls on it from a different direction.

What are Dirac metals?

The quality of conduction in normal metals like gold and silver depends on the way energy depends on the momentum of electrons.

Dirac metals differ from normal metals in that the energy depends linearly on the momentum. This difference is responsible for their unique properties.

Semi-Dirac metals behave like Dirac metals in one direction and like normal metals in the perpendicular directions.
