A naive semiconductor device physicist would think you can't go much further than that without some kind of revolution in the way we think about the physics of our devices.

一个 naive 的半导体器件家会认为，如果不改变我们对器件的解方式，就无法取得更大的进展。

An LED is a type of diode or semiconductor device that emits light when electrons flow through layers of crystalline inorganic material.

LED 是一管或半导体器件，当电子流过结晶无机材料层时会发光。
