Patent ID: 8779474

Claim:
An electric device with a body having a resistor comprising a phase change material being changeable between a first phase and a second phase via crystallization initiating at an interface between crystalline and amorphous materials, the resistor having an electric resistance which depends on whether the phase change material is in the first phase or the second phase, the resistor being able to conduct a current for enabling a transition from the first phase to the second phase, the phase change material being a fast growth material, wherein the phase change material is a composition of formula Sb 1−c ,M c , with c satisfying 0.05≦c≦0.61, and M being one or more elements selected from the group of Ge, In, Ag, Ga, Te, Zn and Sn, wherein the phase change material comprises In or Sn in concentrations which range in total between 5 and 30 atomic percent.
