According to our studies below, by inserting 3 nm MgO layer at the top and 4 nm at the bottom interfaces of the trilayers, we can obtain steady performance. ÇóÈóÉ«Õâ¶ÎÓ¢ÎÄ£¬Ð»Ð» |

| In general, there are discontinuities in the 1 nm MgO layer. Thus the thickness of the film must be less than 1 nm to ensure its continuity. As shown in the following diagram, we can obtain steady performance by inserting a layer of 3 nm MgO at the top and 4 nm at the bottom of the trilayers. |

( ¸Ðл½±ÉÍ!! ) Invisible voids in MgO can be overcome by employing a 3-layer composite of the same material. __________ measurements appear uniform when 1-nm MgO is in between 3-nm and 4-nm thick MgO on top and bottom respectively. Our paper shows how much thicker film are needed to get reliable performance out of 1-nm MgO. __________ = Ò×ÊÜ MgO ÎïÖʼä¶ÏµÄÎïÐÔ |
