Predicting mechanical properties and buckling behavior …
In this paper, mechanical properties and buckling behavior of single-walled silicon carbide nanocones (SWSiCNCs) are studied using a finite element method. The elastic moduli of SWSiCNCs with different dimensions including different apex angles and lengths are presented. For large apex angles, it is shown that the effect of nanocone length on the elastic modulus can be neglected. Besides, the

Pure silicon wafers Pure silicon boules of 300 mm diameter and 30 ft long, can weigh up to 400 Kg. These boules are sliced into thin disks (wafers) using diamond saws. Standard sizes of wafers are: 100 mm (4”) diameter x 500 µm thick.150 mm (6”) diameter x 750 µm thick.
Structural Properties of Liquid SiC during Rapid …
The rapid solidifiion of liquid silicon carbide (SiC) is studied by molecular dynamic simulation using the Tersoff potential. The structural properties of liquid and amorphous SiC are analyzed by the radial distribution function, angular distribution function, coordination nuer, and visualization technology. Results show that both heteronuclear and homonuclear bonds exist and no atomic
