    Pressure-induced band-gap energy increase in a metal iodate 
    Liang, Akun; Shi, Lan-Ting; Turnbull, Robin; Manjón, Francisco-Javier; Ibáñez, Jordi; Popescu, Catalin; Jasmin, M.; Singh, Jaspreet; Venkatakrishnan, Kanchana; Vaitheeswaran, Ganapathy; Errandonea, Daniel (AMERICAN PHYSICAL SOCIETY, 2022-12-09)
    [EN] A wide band gap is one of the essential requirements for metal iodates to be used as nonlinear optical materials. Usually, the band gap of these materials decreases under the application of pressure. Herein, we introduce ...
