A novel polymerizable organosilyl-modified Dawson-type polyoxometalate (POM) [α2-P2W17O61{CH2 C(CH3)COO(CH2)3Si}2O]6− (1) was synthesized as both Me 2 NH 2 + salt (Me2NH2-1) and H+ form (H-1). They were characterized with complete elemental analys

We have studied the effects of disorder on surface stress during oxidation. The surface stress change during ion bombardment and the following plasma oxidation on Si(100) was measured by means of an optical microcantilever technique. We have found co

We present the evolution of surface stress of Si (100) at the oxide film thickness from 0 to 5 nm. Using micromechanical cantilevers, we have measured surface stress evolution during plasma oxidation with applying positive bias to the samples and obs

We report the real-time observation of the stress change during sub-nanometer oxide growth on the Si(100) surface. Oxidation initially induced a rapid buildup of tensile stress up to -1.9 × 10(8) N m(-2) with an oxide thickness of 0.25 nm, followed

We have studied plasma oxidation of silicon surfaces using real-time ellipsometry. The real time observation shows a strong dependence of the plasma oxidation on the plasma density and dc bias. The results clearly reveal that the direction reaction o
