Carrier Localization, Metal-Insulator Transitions and Stripe Formation in Inhomogeneous Hole-Doped Cuprates
Abstract
We propose a unified approach for describing the carrier localization, metal-insulator transitions (MITs) and stripe formation in high-Tc cuprates. The ground-state energy of a carrier interacting with a defect and with lattice vibrations is calculated within the continuum model and adiabatic approximation. At low doping levels, hole carriers in La-based systems with large-radius dopants are localized near the dopants with the formation of hydrogenic impurity centers.
