Abstract

Bipolar resistive switching properties and endurance switching behavior of the neodymium oxide (Nd?O?) thin films resistive random access memory (RRAM) devices for a high resistive status/low resistive status (HRS/LRS) using a low temperature supercritical carbon dioxide fluid (SCF) improvement post-treatment process were investigated. Electrical and physical properties improvement of Nd?O? thin films were measured by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and current versus voltage (I-V) measurement. The metal-like behavior of ohmic conduction mechanism and metallic cluster reaction of hopping conduction mechanism in initial metallic filament path forming process of the SCF-treated thin films RRAM devices was assumed and discussed. Finally, the electrical conduction mechanism of the thin films RRAM derives for set/reset was also discussed and verified in filament path physical model.

See more Neodymium products. Neodymium (atomic symbol: Nd, atomic number: 60)is a Block F, Group 3, Period 6 element with an atomic weight of 144.242. Neodymium Bohr ModelThe number of electrons in each of Neodymium's shells is 2, 8, 18, 22, 8, 2 and its electron configuration is [Xe] 4f4 6s2. The neodymium atom has a radius of 181 pm and a Van der Waals radius of 229 pm. Neodymium was first discovered by Carl Aer von Welsbach in 1885. In its elemental form, neodymium has a silvery-white appearance. Neodymium is the most abundant of the rare earths after cerium and lanthanum. Neodymium is found in monazite and bastnäsite ores. It is used to make high-strength neodymium magnets and laser crystal substances like neodymium-doped yttrium aluminum garnet (also known as Nd:YAG). The name originates from the Greek words neos didymos, meaning new twin.
