Witryna19 lis 2003 · ABSTRACT Total ionized impurity densities ( ND + NA) from 7×10 13 to 3×10 17 cm −3 are determined for epitaxial samples of n ‐type GaAs by analyzing mobility and carrier concentration data as a function of temperature with the Brooks‐Herring formula for ionized impurity scattering.
WitrynaThe impurity pinning of the charge density waves that exhibit three-dimensional order due to interchain coupling is investigated in the model of Fukuyama and Lee by taking account of phase distortions in the transverse directions as well as in the chain direction. Calculated adiabatic potentials elucidate the presence of metastable states, which is …
Witryna31 maj 2024 · For a magnetic impurity embedded in a Mott insulator, our findings suggest that the emergence of a pair of peaks at the Hubbard band edges in the impurity density of states spectra provides strong evidence that the host Mott insulator is a U (1) quantum spin liquid with a spinon Fermi surface.
