【求助】現(xiàn)在有什么軟件可以準(zhǔn)確計(jì)算出晶體的能帶能隙呢 已有11人參與

| 我想從理論上對(duì)晶體的能帶結(jié)構(gòu)進(jìn)行分析計(jì)算,可是得出的結(jié)果與實(shí)驗(yàn)值差距較大,只能定性的分析。我想問(wèn)下有沒(méi)有什么方法可以準(zhǔn)確計(jì)算出能帶結(jié)構(gòu)?哪位老師知道指點(diǎn)一下?盡量詳細(xì)些,謝謝! |

The GW method Calculations of ground-state and excited-state properties of materials have been one of the major goals of condensed matter physics. Ground-state properties of solids have been extensively investigated for several decades within the standard density functional theory. Excited-state properties, on the other hand, were relatively unexplored in ab initio calculations until a decade ago. The most suitable approach up to now for studying excited- state properties of extended systems is the Green function method. To calculate the Green function one requires the self-energy operator which is non-local and energy dependent. In this article we describe the GW approximation which has turned out to be a fruitful approximation to the self-energy. The Green function theory, numerical methods for carrying out the self-energy calculations, simplified schemes, and applications to various systems are described. Self-consistency issue and new developments beyond the GW approximation are also discussed as well as the success and shortcomings of the GW approximation. |
