Wannier excitons are found in semiconductor crystals with small energy gaps and high dielectric constant.

Highly symmetric semiconductor crystals tend to produce a decent valley degeneracy.

He was also involved in studies of semiconductor crystals.

In a regular semiconductor crystal, the band gap is fixed owing to continuous energy states.

On top of this layer they deposited two extremely thin layers of different semiconductor crystals.
