a-axis NIS tunnel junctions using LaSrCuO4

ORAL

Abstract

Planar tunneling in NIS structures with crystalline order reveals the density of states largely focused in the tunneling direction. Earlier experiments with a-axis YBCO showed an unexpected strongly broken particle hole symmetry in the CuO bond direction. Here we report on work to make similar structures with a-axis LaSrCuO4.
