Especially, the difference of the nearest-neighbor hopping integral is due to the effect of the curvature of the carbon nanotubes. So, in fact there is a very narrow energy gap near the Fermi energy of unsquashed metallic zigzag carbon nanotubes, and, a slighter deformation is required to open a considerable energy gap in metallic zigzag carbon nanotubes than that in armchair nanotubes.

特別是，最近鄰格點之間的躍遷積分的變化與碳納米管的曲率緊密相關(guān)丝袜AV观看一区，因此實際上全国亚洲最大的黄色网站，理想金屬型 zigzag 碳納米管本身具有微小能隙，而施加比 armchair 碳納米管小的多的壓縮量国产免费黄片视频，就可以使金屬型 zigzag 碳納米管在費米能處打開相當(dāng)?shù)哪芟丁?/p>

Based on the perturbation theory,the influences of the Fermi resonance interaction between the two and three vibronic levels on the level energy,wavefunction,and the spectral line intensity are investigated in detail respectively.

Furthermore, when several bands near the Fermi surface are taken into account, we find that the interband gaps within the unoccupied bands are generally smaller than those of the occupied bands, indicating that the electron can hop from one band to another which is much easier than the hole.

而且新超碰免费男人网站，當(dāng)研究費米能級附近的能帶時，發(fā)現(xiàn)未占有帶的帶隙總體上要小于占有帶的帶隙亚洲涩图欧美，這表明在考慮聲子參與的情況下色欲天天婬色婬香综，電子在帶間的跳躍要比空穴容易得多欧美一级专区。

The analyses of electronic structures shows that the catalytic reactivities for H2 adsorption of the different surfaces are dependent on the numbers of s orbital bonding electrons around Fermi level for the uppermost layer metal atoms which interact directly with H2. It is easy to form vacancy for hydrogen atoms next to iron atom, which indicates that hydrogen atom cannot be escaped, but it is difficult to from vacancy for hydrogen atoms next to magnesium atom, which indicates that hydrogen atom can be escaped. Hence it is thought that the change of dehydrogenating properties of MgH2 with or without a little iron addition attributes to the weakened bonding between magnesium and hydrogen.

分析電子結(jié)構(gòu)發(fā)現(xiàn)：空位缺陷有助H2吸附于Mg表面97社区精品视频在线观看，與Mg(0001)表面最上層與H2直接產(chǎn)生吸附作用的金屬原子在費米能級附近s軌道的成鍵電子數(shù)密切相關(guān)；在Fe合金化MgH2體系中国产A级高清视频毛片，與合金化元素Fe近鄰的H原子形成空位的難度增加欧美性爱频道，H原子較難釋放；與Mg近鄰的H原子形成空位的難度減少国产盗摄一区，H原子容易釋放99re热自拍偷拍；Fe合金化導(dǎo)致Mg-H之間存在較弱的成鍵作用国产黄色片欧美黄色片，因此，MgH2體系的解氫性能得到提高。

The world's most powerful telescope for observing the universe in high-energy gamma-ray light, the observatory was originally called the Gamma-ray Large Area Telescope, but was rechristened after Italian scientist Enrico Fermi once the telescope was up and running in space.

Compared to the semiconductor NCs, metallic NCs as floating gates possesses several advantages, such as larger change of electric capacity, stronger coupling with the conduction channel, a wide range of available work functions, higher density of states around the Fermi level, and a smaller energy perturbation due to carrier confinement.
