germanium

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

1 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。

2 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。

3 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。
