Distinct Pairing Symmetries in $N{d}_{1.85}C{e}_{0.15}Cu{O}_{4-y}$ and $L{a}_{1.89}S{r}_{0.11}Cu{O}_4$ Single Crystals: Evidence from Comparative Tunnelling Measurements

We used point-contact tunnelling spectroscopy to study the superconducting pairing symmetry of electron-doped $N{d}_{1.85}C{e}_{0.15}Cu{O}_{4-y}$ (NCCO) and hole-doped $La_{1.89}Sr_{0.11…
