Handling Notes

1. Elastomer bonding is recommended for this material, due to some of its characteristics not amenable to sputtering like brittleness, low thermal conductivity, etc.

Chemical Elements

Selenium

Selenium is a chemical element originated from Moon (with the Greek name selene). It was first mentioned in 1817 and observed by J. Berzelius and G. Gahn. The isolation was later accomplished and announced by J. Berzelius and G. Gahn. “Se” is the canonical chemical symbol of selenium. Its atomic number in the periodic table of elements is 34 with location at Period 4 and Group 16, belonging to the p-block. The relative atomic mass of selenium is 78.96(3) Dalton, the number in the brackets indicating the uncertainty.
