The colour depends on the properties of the semiconductor, and these can be tuned to produce light that is similar to natural daylight but with virtually no ultraviolet or heat.
光的颜色取决于半导体的特性,可以对这些特性加以调试以发出与自然日光相近的灯光但却几乎不含紫外线或热量。
However, unlike the semiconductor silicon, graphene has no gap between its valence and conduction bands.
然而,与半导体硅不同,石墨烯的价带和导带之间没有带隙。
That is no longer an issue, thanks to modern semiconductor controls.
但因为现代的半导体控制技术,这不久就不是问题了。
