Abstract:
1. A resistance change element comprising: a first conductive layer; a second conductive layer; and a memory layer provided between the first conductive layer and the second conductive layer and capable of reversibly transitioning between a first state and a second state due to at least one of a voltage and a current supplied via the first conductive layer and the second conductive layer, a resistance of the second state being higher than a resistance of the first state, wherein the memory layer includes niobium oxide, and one of a (100) plane, a (010) plane, and a (110) plane of the memory layer is oriented in a stacking direction from the first conductive layer toward the second conductive layer, and wherein a ratio of an intensity at a binding energy of 205 eV to an intensity at a binding energy of 207.5 eV of X-ray photoelectron spectroscopy of Nb included in the memory layer is 0.062 or less.
