Spin-Lattice Relaxation Times of Single Donors and Donor Clusters in Silicon
Spin-Lattice Relaxation Times of Single Donors and Donor Clusters in Silicon
An atomistic method of calculating the spin-lattice relaxation times (T₁) is presented for donors in silicon nanostructures comprising of millions of atoms. The method takes into account the full band structure of silicon including the spin-orbit interaction. The electron-phonon Hamiltonian, and hence, the deformation potential, is directly evaluated from the …
