To observe the chemical mechanical polishing (CMP) process at atomic scale, reactive force field molecular dynamics (ReaxFF-MD) was employed to simulate of 6 H-SiC under three conditions: dry, pure water, and H2O2 solution. This study examined reactants on surface during reaction in solution, along with dissociation adsorption processes water molecules. The mechanisms for atom removal CMP were elucidated. Variations number different bonds over time changes amorphous SiC atoms across various...
The Changbaishan volcano (CBV) located on the border of China and North Korea, is one most dangerous active volcanoes Earth. CBV has experienced two “unrest periods” since 2000C.E. with uplift, increased 3He/4He ratio gas emissions seismicity frequencies. During intermediate “rest period”, subsidence occurred particularly eastern part Tianchi caldera. Whereas magmatic system beneath likely responsible for surface deformation, several factors can...
