a, and b Thermoelectric EFF values for all p-type-doped a and n-type-doped b three-layered hetero-structures, where hetero-structures on the x-axis are ordered by increasing EFF value. Points highlighted in red and green denote hetero-structures returned most frequently as the optimal structure by a BO model searching for the p-type- and n-type-doped structures, respectively, with maximum EFF value. c, d Pie chart showing the distribution of optimal thermoelectric structures returned in 500 independent BO searches for the p-type-doped c and n-type-doped d materials with maximum EFF value
