摘要：

The magnetoconductance Δσ(B) of a series of high-quality quasicrystals and approximants is discussed in terms of quantum interference effects. The Δσ(B) data cover a wide temperature range from 0.1 to 200 K and magnetic fields as high as 20 T. Strong electron interactions are found, through inelastic electron-electron scattering as the main inelastic-electron-scattering mechanism and an enhanced electron screening. Evidence for a suppression of the quantum interference effects close to the metal-insulator transition in quasicrystals are discussed. © 1995 The American Physical Society.
