Unformatted text preview: a simple translation. Question: a) Crystalline silicon forms a diamond crystal. Is Si bulk ­inversion symmetric? b) Gallium arsenide forms a zinc ­blende crystal. Is GaAs bulk ­inversion symmetric? SHOW WORK! Hint: Write down the coordinates of the lattice vectors of the various atoms of these crystals. Then invert all coordinates, and determine if the new coordinate positions can be translated by a Bravais lattice vector to be equal to the old coordinates....
