Name That Semiconductor

Do you mean superconductors: i.e. substances with very low resistance when close to zero Kelvin?

If so google.... superconductor.

Tnx. Randall for your reply , sorry i cant be more helpfull , i heard years back about

this new''semicoductor'' or ''superconductor'' as you mentioned.This particular element actually floats in a certain range of Kelvin degrees of liquid helium , at that time it was a new discovery and now i am trying to find out its name , composition and how it has developed in real application.

Thanks Again
