At 3 nanometers, ordinary titanium dioxide breaks its symmetry and turns ferroelectric
SMRTR summary
Titanium dioxide becomes ferroelectric below 3nm thickness due to crystal symmetry breaking, retaining this property down to 1nm. Its existing role in semiconductor manufacturing makes it a promising candidate for denser, lower-power memory and logic devices.
