We can change the behavior of a pure silicon crystal by doping it.

当纯矽的晶体和其它不纯物混杂在一起，矽的本质会改变。

The method of signal-to-noise ratio of pure silicon sample, in the opinion of the author, is even better than other methods.

作者认为，采用纯硅样品的信噪比法要比其它方法更为方便可靠。

Correctly doping the ultra-thin channels that the consortium hopes to use is simply too difficult hence the decision to do without dopants altogether and build channels out of pure silicon.

ECONOMIST: Transistors

The consortium's technology builds its transistors inside a sliver of pure silicon, laid on top of an insulator, which in turn sits on top of a standard wafer, the substrate on which transistors are constructed.
