"materials that lose electrical polarization at atomic scales, overcome reducing titanium dioxide to <3 nm thick layer enabling ferroelectric properties, maintained down to approximately 1 nm... ferroelectric materials switch electric polarizations at much lower voltages... properties retained across various substrates, atomic layer deposition synthesizable at <400°C... CMOS fabrication compatible, scalable pathway toward next-generation 3D integrated microelectronics"
