WebGroup-IV monochalcogenides, such as germanium selenide (GeSe), are strongly anisotropic semiconducting van der Waals crystals isoelectronic to black phosphorus, with superior stability in air conditions. High optical absorption, good conductivity, and band gap ranging from 1 to 2 eV make these materials suit WebEstimates from literature reviews of the average macular pigment optical density for a 2° field vary from 0.35 ( Vos, 1972) to 0.50 ( Wyszecki and Stiles, 1982 ).
