Hiroki Kamitake、Kosuke Ohara、Mutsunori Uenuma 等 7 位作者2012-05-01OpenAlex

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 1012cm-2was formed on a SiO2at low temperature by specific adsorption of TD. The hysteresis of the MOS capacitor with nanodot array formed uti…
