A particular attention is paid to removal of spin degeneracy caused by the rotoinversion asymmetry of a (001) heterointerface between two diamond-lattice materials. Consequences of the spin splitting on the electron spin relaxation time is discussed.3 pages, 1 figureMesoscale and Nanoscale Physicstext
