摘要

The characteristics of p-channel Ge/Si hetero-nanocrystal based MOSFET memory have been investigated numerically considering mainly hole-tunneling process. Owing to the advantages of a compound potential well and a higher band offset at the valence band compared with the p-channel Si nanocrystal based MOSFET memory and n-channel Ge/Si hetero-nanocrystal based MOSFET memory, the present structure shows that the holes have a longer retention time. Moreover, this kind of device keeps on having high-speed writing/erasing in the direct-tunneling ultrathin oxide regime. It would be expected to solve the contradictory problem between high-speed programming and long retention, therefore, the performance would be substantially improved.
