"ferroelectrics face challenges minimizing domain size due to atomic vibrations' collective nature, overcome focusing on phonon decoupling in subatomic ferroelectric brownmillerite... when tetrahedral layers vibrate, adjacent octahedral layers remain mostly unaffected, enabling domains' selective formation within tetrahedral layers when electric field applied... ferroelectric capacitors, thin-film transistors... memory devices 10's of times smaller/ faster... smartphone, computer capacity/ processing speed significantly improved"
