germanium

It s also the first germanium laser to operate at room temperature..这同样也是第一速在室温下得到控制的锗激光。

The researchers inject pairs of electrons and holes into the germanium..研究者们注射成对的电子和凹陷到锗中。

Changing the angle and length of the bonds between germanium atoms also changed the energies required to kick their electrons into the conduction band..改变锗原子的连接角度和长度的同时，将它们的电子踢到传导带所需的能量也变化了。

锗英释中释na brittle crystalline grey element that is a semiconducting metalloid, occurring principally in zinc ores and argyrodite: used in transistors, as a catalyst, and to strengthen and harden alloys
