Tunable two-dimensional or three-dimensional electron gases by submonolayer La doping of SrTiO3
First-principles calculation was used to study the structural and electronic features of the low-dimensional oxide structure, SrTiO3/Sr1−xLaxTiO3 (x= 0.25) superlattices, constructed by submonolayer low-dimensional La doping into SrTiO3. We demonstrate a dimensionality crossover from three-dimensional (3D) to two-dimensional (2D) electronic behavior in the system. Two types of carriers, one con...
متن کاملLimit of the electrostatic doping in two-dimensional electron gases of LaXO3(X = Al, Ti)/SrTiO3
In LaTiO₃/SrTiO₃ and LaAlO₃/SrTiO₃ heterostructures, the bending of the SrTiO₃ conduction band at the interface forms a quantum well that contains a superconducting two-dimensional electron gas (2-DEG). Its carrier density and electronic properties, such as superconductivity and Rashba spin-orbit coupling can be controlled by electrostatic gating. In this article we show that the Fermi energy l...
متن کاملNonlinear screening in two-dimensional electron gases.
We have performed self-consistent calculations of the nonlinear screening of a point charge Z in a two-dimensional electron gas using a density functional theory method. We find that the screened potential for a Z=1 charge supports a bound state even in the high-density limit where one might expect perturbation theory to apply. To explain this behavior, we prove a theorem to show that the resul...
متن کاملLocalization of two-dimensional electron gas in LaAlO3/SrTiO3 heterostructures
We report strong localization of two-dimensional electron gas in LaAlO3/SrTiO3 epitaxial thin-film heterostructures grown on (LaAlO3)0.3-(Sr2AlTaO3)0.7 substrates by using pulsed laser deposition with in situ reflection high-energy electron diffraction. Using longitudinal and transverse magnetotransport measurements, we have determined that disorder at the interface influences the conduction be...
متن کاملTunneling between parallel two-dimensional electron gases.
The tunneling between two parallel two-dimensional electron gases has been investigated as a function of temperature T , carrier density n, and the applied perpendicular magnetic field B. In zero magnetic field the equilibrium resonant lineshape is Lorentzian, reflecting the Lorentzian form of the spectral functions within each layer. From the width of the tunneling resonance the lifetime of th...
