germanium造句怎么写

In computers, these diodes are primarily germanium or silicon crystals.

a rare reddish-gray mineral consisting of a copper iron germanium sulfide.

According to the group s theoretical work, phosphorous doping works best at 1020 atoms per cubic centimeter of germanium, Kimerling explains.

So far, the group has developed a technique that can add 1019 phosphorous atoms to each cubic centimeter of germanium, and we already begin to see lasing, Kimerling says.

It s also the first germanium laser to operate at room temperature.

A computer chip made from organic molecules rather than silicon or germanium.

Changing the Angle and length of the bonds between germanium atoms also changed the energies required to kick their electrons into the conduction band.
