ABSTRACT

It is inferred from the position of the 2Δ peak in the electron light scattering spectra that in a sample with high Tc≈90 K the ratio 2Δ/Tc is approximately equal to 6 and 7 for different polarizations, while in overdoped samples with Tc≈40 and 35 K the 2Δ peak is observed only in x′y′ polarization with a substantially lower ratio 2Δ/Tc≈3.2. With decreasing Tc in Tl2Ba2CuO6+x crystals, a transition occurs from strong to weak coupling; the superconducting gap remains anisotropic at different doping levels. More... »
