【#Tech24H】Scientists at the University of California, Berkeley, Lawrence Berkeley National Laboratory, and SLAC National Accelerator Laboratory have found that reducing the thickness of a titanium thin film to below 3 nanometers can convert it into ferroelectric materials, exhibiting spontaneous polarization that can be switched by an external electric field. This ferroelectric behavior remains stable even at thicknesses as thin as about 1 nanometer. This breakthrough opens a new path for mass-producing computing chips that run faster and consume less power. [ By Zhang Liyan | Tang Ruohan ]
