By the treatment of mechanical chemistry method, in Si plate non-active zone isintroduced to defect. Under thermal treatment few of heavy metal impurity candiffuse and deposit in the defect, so that to reduce harmful impurities impact ondevices working zone, improve the properties of devices, the...

Extreme manufacturing is specifically manifested in manufacturing with extremely high energy density, ultrahigh precision, extremely small spatial and temporal scales, extremely intensive fields, and giant systems with extreme complexity and number of fa
An element, simply put, is afundamental unit of matter that cannot be easily broken down. It consists of a specific number of protons and variable neutrons and electrons. All of matter is made of these 118 elements, combined in various ratios and kept in different states, like solids. ...

a few remarks can be made, echoing the findings from the Si case study. As expected, the overall proportion of inelastically scattered electrons increases with specimen thickness, i.e. in the thin region, 73% of all electrons are in the zero-loss window, while this number decreases to 39...
