Nanodot-type floating gate memory with high-density nanodot array formed utilizing listeria ferritin

Abstract

We formed a high-density two-dimensional nanodot array by utilizing Ti-binding Dps (TD) which is a Listeria ferritin with Ti-binding peptides. A high-density nanodot array over 10 12 cm -2 was formed on a SiO 2 at low temperature by specific adsorption of TD. The hysteresis of the MOS capacitor with nanodot array formed utilizing TD was larger than that of the MOS capacitor fabricated utilizing ferritin. This research contributes to realizing future memory devices.
