Density Functional Theory Simulations of Semiconductors for Photovoltaic Applications: Hybrid Organic-Inorganic Perovskites and III/V Heterostructures
Figure 12
Effective lineup of the LDA planar averaged potentials for GaP and GaAs in a short-period GaAs(8)/GaP(8) superlattice. The planar averaged potentials for bulk GaP and strained GaAs are represented in green and red, respectively. The potential curve of bulk GaP has been downshifted by −0.66 eV in order to fit into the GaP layer of the potential curve of the GaAs(8)/GaP(8) SL. The potential curve of strained GaAs has been upshifted by 0.62 eV in order to fit into the GaAs layer of the potential curve of the GaAs(8)/GaP(8) SL.
