From: A monoclinic semiorganic molecular crystal GUHP for terahertz photonics and optoelectronics

Calculated band structure and density of states (DOS) for GUHP. The energy of the band gap for both temperatures corresponds to the wavelength of the VUV spectral region, which is 166.24 nm (293K) and 166.91 nm (80K).
