這是幫助文件里的說(shuō)明,還是不太懂,假如結(jié)構(gòu)優(yōu)化完畢,想要計(jì)算能帶結(jié)構(gòu),態(tài)密度和布局分析,選哪個(gè)呢? The CASTEP Energy task allows you to calculate the total energy of the specified 3D periodic system, as well its physical properties. In addition to the total energy, the forces on atoms are reported at the end of the calculation. A charge density file is also created, allowing you to visualize the spatial distribution of the charge density using the Materials Visualizer. The electronic energies at the Monkhorst-Pack k-points used in the calculation are also reported, so that you can generate a density of states chart during CASTEP analysis. The Energy task is useful for studying the electronic properties of systems for which reliable structural information is available. It can also be used to calculate an equation of state (i.e. a pressure-volume and/or energy-volume dependence) for high-symmetry systems with no internal degrees of freedom, as long as the Stress property is specified. The CASTEP Properties task allows you to compute electronic, structural, and vibrational properties after the completion of a single-point energy, geometry optimization, or dynamics run on a 3D periodic system. Note. In order to calculate properties using the CASTEP Properties task, the results files from a suitable simulation must be present in the current project. [ 來(lái)自科研家族 骷髏黨 ] |
