Layers of Stripes

Caption

Copper-oxide layers of LBCO (the lanthanum-barium layers would be between these). 3-D superconductivity occurs when current can flow freely in any direction within and between the copper-oxide layers, while 2-D superconductivity exists when current moves freely only within the layers (not perpendicular). The perpendicular orientations of stripe patterns from one layer to the next may be part of what inhibits movement of current between layers.
