The researchers' material of choice is an alloy of germanium, antimony and tellurium.

研究人员选择的材料是镓、锑和碲合金。

To test this idea, he grew crystals of silicon that contained tiny particles of germanium in their lattices.

为了验证这个观点，他研制出了硅晶体，晶体的点阵之间含着细小的锗颗粒。

Kilby built his ICs out of germanium, a rare and unstable material.

Kilby 用锗制造了他的 IC，这是一种稀有且不稳定的材料。

Trace amounts of water, silicon, germanium, or magnesium might also influence a diamond’s shape.

微量的水、硅、锗或镁也可能影响钻石的形状。

These could be a liquid noble gas, germanium and silicon crystals, a refrigerant, or other materials.

这些可能是液态惰性气体、锗和硅晶体、制冷剂或其他材料。

China supplies about 80% of the world's gallium and germanium.

中国供应全球约80%的镓和锗。

Gallium and germanium may also be useful in electric vehicles, nuclear energy and other devices, including weapons.

镓和锗还可用于电动汽车、核能和其他设备，包括武器。

So this is a small sample of germanium, named after Germany, so you can see the wonderful shiny surfaces.

所以这是一个小的锗样品， 以德国命名，所以你可以看到美妙的闪亮表面。

America may source as much as 50% of its germanium supply from China, according to Jefferies, an investment bank.

据投资银行杰富瑞 (Jefferies) 称，美国可能有多达 50% 的锗供应来自中国。

But on July 3rd it brought out a bigger gun, saying that it would impose export controls on gallium and germanium, two metals used in high-end semiconductors.

但7月3日，它又拿出了更大的枪，称将对镓和锗这两种用于高端半导体的金属实施出口管制。
