The total spin relaxation anisotropy is demonstrated for a wide range of structure parameters and temperatures. The spin relaxation rates dependences are derived for GaAs-based heterojunction and triangular quantum well. The calculations show a few orders of magnitude difference in spin relaxation times.14 pages, 5 figuresMesoscale and Nanoscale PhysicsDisordered Systems and Neural Networkstext
