Mass standards could also be constructed from silicon crystals or by other atom-counting methods.

This makes a silicon crystal an insulator rather than a conductor.

A pure silicon crystal is nearly an insulator - very little electricity will flow through it.

In doping, you mix a small amount of an impurity into the silicon crystal.

Pure silicon crystals are very rarely found in nature.

The Russian Government has already spent several million dollars to grow silicon crystals.

Under certain conditions, the silicon crystal actually helped light escape.

His first detector, which used a silicon crystal, was patented in 1906.

While silicon crystals look metallic, they are not, in fact, metals.

The atoms, magnified a billion times, appear as "hills" on a silicon crystal.
