PCB METHOD APPLIED TO MATERIAL DESIGN - COMPUTER-AIDED SYNTHESIS OF BIPBSRCACUOF SUPERCONDUCTOR

An inverse mapping method called PCB (principal component backing), in which the point representing an unknown sample from a low-dimensional principal component subspace is back-projected to the high-dimensiona l original feature space, is proposed. Two sorts of boundary condition s, non-linear inverse mapping and linear inverse mapping, are used to obtain an accurate solution in the PCB method. The method is applied t o the material design of high-T-c superconductors, predicting the comp osition and process conditions for the synthesis of F-doped Bi-based m aterials. Samples in the 'optimal' region with the highest T-c of the Bi-based ceramics have been predicted.
