ABSTRACT
We show an artificially engineered electret with Si nanocrystals embedded in mesoporous silica for nonvolatile memory. We attribute the polarization to from polar layers lying at the interfaces between one-side bonded Si nanocrystals and mesoporous silica matrix. Under external field, the Si nanocrystals could be displaced in the porechannels causing displaced charge distributions and therefore a field-controllable electric polarization. Nonvolatile memory is demonstrated with a metal-oxide-semiconductor field-effect transistor.

    Background: Hot-carrier-injection (HCI) is one of important reliability issue under short-channel effect in modern MOSFET devices especially in nano-scaled CMOS technology circuits. The effect of the hot carrier can be reduced by introducing Lightly-Doped-Drain (LDD) structure on the device. The...
