Pressure dependence of out-of-plane conduction in La2-xSrxCuO4.

چکیده
Pressure dependence of out-of-plane resistivity rc has been investigated in an optimally-doped high-Tc cuprate La22xSr xCuO4. By applying pressure, we found a drastic decrease in rc which reaches 50% at P58 GPa. This surprisingly large P dependence implies that the thermal contraction along the c axis is significantly reflected in the rc(T) curve, leading to a metal-like term; hence La22xSr xCuO4 is essentially characterized as a two-dimensional metal modified with nonmetallic conduction between CuO2 layers. Tunneling is suggested for a possible mechanism for rc . @S0163-1829~96!05138-7#

Coherent versus incoherent transport in layered doped Mott insulators.
There exist strong experimental evidences for the dimensional cross-over from two to three dimensions as La2−xSrxCuO4 compounds are overdoped. In this paper we describe the dimensional cross-over of the layered correlated metal in the gauge theory framework. In particular, we obtain the anomalous exponent 3/2 for the temperature dependence of resistivity observed in overdoped La2−xSrxCuO4 . PAC...
متن کاملMicroscopic Charge Inhomogeneities in Underdoped La2 xSrxCuO4: Local Structural Evidence
We present local structural evidence for the existence of charge inhomogeneities at low temperature in underdoped and optimally doped La2 xSrxCuO4. The inhomogeneities disappear for x 0.2. The evidence for the charge inhomogeneities comes from an anomalous increase in the inplane Cu–O bond length distribution in the underdoped samples as well as evidence for CuO6 octahedral tilt inhomogeneities...
متن کاملEvidence for strong electron–phonon coupling and polarons in the optical response of La2−xSrxCuO4
The normal state optical response of La2−xSrxCuO4 is found to be consistent with a simple multi–component model, based on free carriers with strong electron–phonon interaction, localized polaronic states near 0.15 eV and a mid–infrared band at 0.5 eV. Normal state reflectance and absorbance of La1.83Sr0.17CuO4 are investigated and their temperature dependence is explained. Both, the ac and dc r...
متن کاملNeutron diffraction evidence of microscopic charge inhomogeneities in the CuO2 plane of superconducting La2-xSrxCuO4 (0<or=x<or=0. 30).
High-resolution atomic pair distribution functions have been obtained using neutron powder diffraction data from La2-xSrxCuO4 over the range of doping 0<or=x<or=0.30 at 10 K. Despite the average structure getting less orthorhombic, we see a broadening of the in-plane Cu-O bond distribution as a function of doping up to optimal doping. Thereafter the peak abruptly sharpens. The peak broadening c...
متن کاملChiral plaquette polaron theory of cuprate superconductivity
Ab initio density functional calculations on explicitly doped La2−xSrxCuO4 find that doping creates localized holes in out-of-plane orbitals. A model for cuprate superconductivity is developed based on the assumption that doping leads to the formation of holes on a four-site Cu plaquette composed of the out-of-plane A1 orbitals apical O pz, planar Cu d3z2−r2, and planar O p . This is in contras...
