Popis: Metal/ferroelectric-Si:HfO2/SiN/SiO2/Si structure was fabricated to investigate the charge trapping properties. This device enhances the carrier injection into the nitride from the silicon due to the spontaneous polarization in SiO2:HfO2 layer. Compared with conventional metal/SiO2/SiN/SiO2/Si devices, the proposed devices showed a larger memory window, faster program/erase speeds, and higher endurance with comparable retention properties.
