    "abstract": "We perform the quantitative evaluation of the entanglement dynamics in\nscattering events between two insistinguishable electrons interacting via\nCoulomb potential in 1D and 2D semiconductor nanostructures. We apply a\ncriterion based on the von Neumann entropy and the Schmidt decomposition of the\nglobal state vector suitable for systems of identical particles. From the\ntimedependent numerical solution of the two-particle wavefunction of the\nscattering carriers we compute their entanglement evolution for different spin\nconfigurations: two electrons with the same spin, with different spin, singlet,\nand triplet spin state. The procedure allows to evaluate the mechanisms that\ngovern entanglement creation and their connection with the characteristic\nphysical parameters and initial conditions of the system. The cases in which\nthe evolution of entanglement is similar to the one obtained for\ndistinguishable particles are discussed.",
