Oxide Heterostructure Resistive Memory

Nano Letters, 2013
Resistive switching devices are widely believed as a promising candidate for future memory and logic applications. Here we show that by using multilayer oxide heterostructures the switching characteristics can be systematically controlled, ranging from unipolar switching to complementary switching and bipolar switching with linear and nonlinear on ...

Oxidation-Resistant Gold-55 Clusters

Science, 2002
Gold nanoparticles ranging in diameter from 1 to 8 nanometers were prepared on top of silicon wafers in order to study the size dependence of their oxidation behavior when exposed to atomic oxygen. X-ray photoelectron spectroscopy showed a maximum oxidation resistance for “magic-number” clusters containing 55 gold atoms.

Silicon enhances high temperature oxidation resistance of SIMP steel at 700 °C

, 2020
To understand the role of Si in the oxidation resistance of SIMP steel, steels with three Si levels, 0, 0.58 and 1.22 wt.% (0Si, 06Si and 12Si for short), were tailored to investigate their oxidation behaviors at 700 °C.
