Close the dialog box and open PWE Simulation Parameters dialog. The latter one goes beyond the GGA by considering also the kinetic-energy density as a variable in order to have more flexibility, and hence belongs to the so-called meta-GGA. The estimation of the lattice constant is hence decided by minimizing the energy. VESTA software is used to observe the crystal structure for both BCY and BZY samples. The videos below include an overview of new features in Diamond along with several key improvements and changes in specific areas from earlier software environments. 55% purity after being calcined at 700°C and 1100°C, highscore software lattice constant respectively. We con-sidered five GGA functionals14–16,18 19 as well as the LDA Refs. Although each peak consists of two separate reflections (K α 1 highscore software lattice constant and K α highscore 2 ), at small values of 2 θ the peak locations overlap with K α 2 appearing as a hump on the side of K α 1.
