Hydrostatic pressure reduces the band gap and increases the ZT value of SnS2.
The band gap increases with increasing tensile strain to its maximum value at 6% strain and then decreases.
The crystallized amino acid γ-glycine is a large band gap insulator that shows promise in the fields of photonics and non-linear optics.
