Heterogeneous nucleation of pits via step pinning during Si(100) homoepitaxy

open access: yesNew Journal of Physics, 2017
Using scanning tunneling microscopy (STM), we investigate oxide-induced growth pits in Si thin films deposited by molecular beam epitaxy. In the transition temperature range from 2D adatom islanding to step-flow growth, systematic controlled air leaks ...

Іnfluence of initial defects on the distribution of mechanical stresses and deformations during silicon oxidation

open access: yesТехнологія та конструювання в електронній апаратурі, 2008
Using modern methods, the complex structure of near-surface silicon layers in the “silicon — silicon dioxide” systems has been investigated. The dependencies of the parameters of these layers on oxidation conditions and the characteristics of the initial

Oxides and oxide superconductors :

open access: yes, 1991
Using both measurements and modeling, the elastic and related properties of some oxides and oxide superconductors were studied. The polycrystal elastic constants were measured using a MHz-frequency pulse-echo method between 295 and 4 K and corrected to the void-free state by using a model for a composite material containing spherical particles.

Effect of oxide interface roughness on the threshold voltage fluctuations in decanano MOSFETs with ultrathin gate oxides [PDF]

open access: yes, 2000
In this paper we use the density gradient (DG) simulation approach to study, in 3D, the effect of local oxide thickness fluctuations on the threshold voltage of decanano MOSFETs on a statistical scale.

Adsorption of Acetic Acid Vapors by Inorganic–Organic Nano Materials: Implications for the Inhibition of the “Vinegar Syndrome” in 20th Century Motion Picture Films

open access: yesMolecules
Cellulose acetate (CA) motion picture films are subjected to degradation, especially due to the “vinegar syndrome”, a de-acetylation process catalyzed by high temperature, humidity, and acidity.

Nitric Oxide (NO) [PDF]

open access: yes, 2015
Nitric oxide plays a significant role in atmospheric phenomena and pollution. It helps to create ozone in the lower atmosphere where it is not needed, and again unfortunately helps to remove ozone from the higher levels of the atmosphere where it is ...
