The electrical resistance of single crystal silicon significantly changes under the application of mechanical stress due to the piezoresistive effect.[14] Heavily boron-doped silicon is a type II superconductor with a transition temperature Tc of 0.4 K Silicon in its more common crystalline form was not prepared until 31 years later, by Deville.[26][27] By electrolyzing a mixture of sodium chloride and aluminium chloride containing approximately 10% silicon, he was able to obtain a slightly impure allotrope of silicon in 1854.[28] Later, more cost-effective methods have been developed to isolate several allotrope forms, the most recent being silicene.

Because silicon is an important element in high-technology semiconductor devices, many places in the world bear its name.
