The P-E loops for (Al, Sc, B)N with Sc concentration of a 59% and b 50% for B concentration y = 13%, 16%, 19%, 22%, 25%. The applied electric field maximum is 6 MV/cm. c The energy density W and efficiency η as a function of B concentration for Sc concentration from 47% to 59%. d The energy density of (Al, Sc, B)N in possible concentration of Sc and B. P represents polarization change under electric filed comparing to the initial structure under zero field. Open and solid symbols indicate the polarization during the charging and discharging processes, respectively.
