Role of two-dimensional electronic state in superconductivity in La${}_{2-x}$Sr${}_x$CuO${}_4$

Fumihiko Nakamura, Tatsuo Goko, Junya Hori +3

We have measured out-of-plane resistivity ${\rho }_c$ for La${}_{2-x}$Sr${}_x$CuO${}_4$ under anisotropic pressure. c-axis compression, which decreases ${\rho }_c$, reduces $T_{\mathrm{c}}$ drastical…
