'报告题目：利用Wannier 函数修正DFT的计算,报 告 人：翁谋毅 博士,邀 请 人：吴泉生 特聘研究员,报告时间：2021年12月31日 下午14:30-16:00,报告地点：怀柔园区MA楼224会议室,腾讯会议ID：467 845 686,会议密码：1231,报告摘要：常见的Kohn- Sham DFT计算方法在计算常见的半导体材料的时候往往会低估材料带隙。一般认为，DFT计算得到的总能量关于电荷数目的导数即为电子的本征能量，这一部分的能量在分子体系中可以用delta-scf 的计算方法得到，从而计算分子中电子的本征能量。在固体材料中，由于计算方法的差异，我们无法直接往计算体系中增加电子，需要使用微扰的方法进行，Linear-Response LDA+U 方法是其中的一种方法，我们使用Wannier 函数的方式，直观地在主族元素化合物中进行增加或减少电子的计算，从而得到与实验结果更接近的电子结构。,报告人简介：翁谋毅，博士，清华大学2015年本科毕业，北京大学2020年博士毕业，主要研究内容包括平面波第一性原理的计算方法，锂离子电池正极材料的第一性原理计算，'

Report title: correction of DFT calculation by Wannier function,Reported by: Dr. Weng mouyi,Invited by: Wu Quansheng, distinguished researcher,Report time: 14:30-16:00 PM, December 31, 2021,Report location: conference room 224, Ma building, Huairou Park,Tencent conference ID: 467 845 686,Conference password: 1231,Report summary: the common Kohn - sham DFT calculation method often underestimates the material band gap when calculating common semiconductor materials. It is generally believed that the derivative of the total energy calculated by DFT with respect to the number of charges is the intrinsic energy of electrons. This part of energy can be obtained by delta SCF calculation method in molecular system, so as to calculate the intrinsic energy of electrons in molecules. In solid materials, due to the difference of calculation methods, we cannot directly add electrons to the calculation system, so we need to use the perturbation method. The linear response LDA + U method is one of them. We use the Wannier function to intuitively calculate the increase or decrease of electrons in the main group element compounds, Thus, the electronic structure closer to the experimental results is obtained.,About the reporter: Weng mouyi, doctor, graduated from Tsinghua University in 2015 and Peking University in 2020. His main research contents include the first principle calculation method of plane wave and the first principle calculation of cathode materials for lithium ion batteries,。
'大多数物质中的电子在室温度下处于电子基态的最低能级上，当激发光的频率与电子的特征频率相一致时，电子会对这种光子产生吸收，然后从基态能级到激发态中各个能级上。由于处在激发态的电子不稳定，大多数电子会降落到第一电子激发态的最低能级上，之后，电子再由第一电子激发态的最低能级向基态的各个能级跃迁，在这个过程中，能量以光子的形式释放，产生的光即是荧光'

Most of the electrons in matter are in the lowest energy level of the ground state of the electron at room temperature. When the excitation frequency is consistent with the characteristic frequency of the electron, the electron will absorb the photon, and then from the ground state to each energy level in the excited state. Because the electrons in the excited state are unstable, most of the electrons will fall to the lowest level of the first electron excited state, and then the electrons will transition from the lowest level of the first electron excited state to each level of the ground state. In this process, the energy is released in the form of photons, and the light produced is fluorescence。
'紫外可见吸收光谱是由于分子中价电子的跃迁而产生的。这种吸收光谱决定于分子中价电子的分布和结合情况。分子内部的运动分为价电子运动、分子内原子在平衡位置附近的振动和分子绕其重心的转动。因此分子具有电子能级、振动能级和转动能级。通常电子能级间隔为1至20eV,这--能量恰落在紫外与可见光区。每一个电子能级之间的跃迁,都伴随着分子的振动能级和转动能级的变化，因此，电子跃迁的吸收线就变成了内含有分子振动和转动精细结构的较宽的谱带。'

The UV Vis absorption spectrum is due to the transition of valence electrons in molecules. The absorption spectrum depends on the distribution and binding of valence electrons in the molecule. The internal motion of molecules can be divided into valence electron motion, the vibration of atoms near the equilibrium position and the rotation of molecules around their center of gravity. Therefore, the molecule has electronic energy level, vibrational energy level and rotational energy level. Generally, the energy levels of electrons are separated by 1 to 20 EV, which is located in the ultraviolet and visible regions. Every transition between the electronic energy levels is accompanied by the changes of the vibrational and rotational energy levels of the molecule. Therefore, the absorption line of the electronic transition becomes a wider band containing the vibrational and rotational fine structure of the molecule.。
