| Research Abstract |
We had made a study on next generation high density ferroelectric data storage based on scanning nonlinear dielectric microscopy. We have succeeded in forming world smallest ferroelectric single nano-domain dot with the size of 2.8nm in diameter. Also, we had achieved the memory density of 4Tbit/inch^2 in actual information recording which requires an abundance of bits to be packed together.
