• low-fidelity: Band gaps computed using the generalized gradient approximation (GGA), E GGA g . • high-fidelity: Band gaps computed using the Heyd-Scuseria-Ernzerhof (HSE06) exchange-correlation functional, E HSE06 g . The GGA level of theory is computationally feasible for these systems but is known to underestimate E g by 30%. The HSE06 level of theory is expected to be on par with experimentally determined band gaps but is computationally restrictive. We omit a detailed comparison of the computational methods and estimate the HSE06 level of theory to be an order of magnitude more expensive than the GGA level.
