Tuning the band gap and polarization of BaSnO 3 /SrSnO 3 superlattices for photovoltaic applications

Band gap and polarization are two important quantities for enhancing the performance of photovoltaic materials. Based on first-principles calculations, we demonstrate that direct band gap and hybrid improper ferroelectric polarization coexist in BaSnO /SrSnO superlattices. Furthermore, the band gap...
