diode

Each diode is cut from a wafer of crystals layered over a base of silicon or sapphire.

每一个二极管都从硅（或者蓝宝石为衬底的）晶片上切割下来。

The metal oxide semiconductor field effect transistor (MOSFET) works on a similar principle, but the diode is buried within the MOSFET.

在金属氧化物半导体场效应晶体管（MOSFET）的作品在一个类似的原则，但二极管的MOSFET内掩埋。

Far from it. Devices are being built that can manipulate phonons, allowing them to flow in one direction only, for example - the thermal equivalent of a diode.

可以操作声子并只让它们向一个方向流动的设备正在被建造，这是二极管的热等价物。
