4 天之前 · The electronic properties can be further explained with the PDOS plot in Fig. 2 (b). The lower core level, ranging from −19.1 eV to −18.1 eV, originates from the s states from both Pb and O atoms. The metallic d states from the Pb atom can be found at an upper core level, ranging from −15.1 eV to −13.3 eV.

DOS profile and the most relevant projected DOS (PDOS) for Pb and O atoms are depicted in Figure 3. Following the notation adopted by Payne et al for β-PbO 2 , 7 it has been identified three...

分波态密度（Projected Density of State, PDOS），是将态密度投影到每个原子轨道之后得到的态密度的分量。 从分波态密度中，我们可以分析每个原子分别对态密度的贡献，甚至每个原子的每个原子轨道（也就是s、p、d、f轨道）对态密度的贡献。

最大PBO超频：防掉压4级，AI core Curve Optimizer Magnitude普通体质设置15-18，Max CPU Boost Clock Override设置200MHZ，2核心睿频5.05ghz，全核4.8ghz (p95压测4.775-4.825波动)。 5800X的上机试用结论： PBO2.0不代表你Boost Clock开到200MHZ就是最大收益，体质和散热一起决定实际频率，在我的7热管风冷散热环境下，Boost Clock开到50MHZ烤P95反而单核全核全上了4.9ghz，Boost Clock开到200MHZ确实双核有5.05ghz但全核掉到4.8ghz，原因是电压更高 …

通俗的说，PBO就是AMD开发的一种超频技术，在你供电、温度允许的情况下，系统自动给CPU进行更加激进超频。 适合一些不会手动超频又想体验超频性能的玩家们。 比如说3600X正常睿频 频率是在3.8-4.4，如果开启PBO后会超过4.4，体质好的甚至可以到达4.6 4.7。 但是为什么我之前一直没有教大家怎么去开启，也不推荐你们去开启呢？ 就是因为之前的PBO我感觉没有必要开启，对于 ZEN3 的CPU来说 电压太高，频率调整不智能，打个英雄联盟，CPU温度都能达到90度， …

2020年3月27日 · Analysis of the ACBN0 calculated total and partial density of states (PDOS), figure 1(b), shows that the VBM is dominated by O 2p states, consistent with the expected large charge transfer from Pb to O. The CBM in contrast shows Pb 6s and O 2p states as expected.
