摘要: Abstract The residual resistivity of diluted (Ga,Mn)As magnetic semiconductors with native compensating defects (As-antisites, Mn-interstitials) is calculated from first principles using the Kubo–Greenwood linear response theory. concentration variations reflect strength impurity scattering and number carriers. In agreement a recent experiment, resistivities are strongly correlated alloy Curie temperatures evaluated in terms classical Heisenberg Hamiltonian.
