Can Materials Explorer create fcc, bcc, etc crystal unit cell?
[A] Yes. The Main module of Materials Explorer can create a unit cells of type fcc, bcc, simple cubic and diamond. And the Crystal Builder Module can create a unit cell belonging to any space group from given an asymmetric unit as input. [Q] I would like to stack two unit cells with different structures and lattice constants on top of each other. But, I found the Error Message ‘Upper “X*a” must be equal to lower.’ during the initial setting stage. What should I do? [A] In order to stack two unit cells the width and length of the the adjoining faces must be the same size. The user has control over these values through the choice of the unit cell size and the number of of times that the unit cell is replicated in the a and b directions. For example, suppose the upper unit cell has the following lattice constants (in Angstroms and degrees) a=4.0, b=5.0 and c=3.0 and alpha=beta=gamma=90. If the lower cell has the same lattice constants then one can carry out a layer-type simulation as long
