💡 Novelty & Significance:
Machine learning-guided design identified tungsten bronze oxides with Bi/Ge co-substitution, yielding a ceramic with high permittivity (~185), ultra-low loss (<0.0005), and near-zero temperature coefficient (≤±30 ppm/°C). Strong Ge–O bonds sustain polar displacements during thermal expansion. Prototype capacitors exceed commercial benchmarks, demonstrating how ML can navigate vast compositional spaces to discover temperature-stable, low-loss, high-κ dielectrics for miniaturized electronics.
