WebFeb 21, 2024 · The reciprocal net is determined by (defined by) the reciprocal vectors: a 1 * & a 2 * (for the substrate) and b 1 * & b 2 * (for the adsorbate) Initially we will consider just the substrate. The reciprocal vectors are related to the real space unit cell vectors by the scalar product relations: a 1. a 2 * = a 1 *. a 2 = 0. and. a 1. a 1 * = a 2 ... WebFor the reciprocal-space GWA calculation, scalability can be attained by parallelizing over the conduction bands. In real space, the r-vectors in the irreducible real-space unit cell are an appropriate variable for a scalable parallel implementation. 335 The number of vectors in the irreducible real-space unit cell is directly proportional to system size and hence the …
