Abstract:
A phase change material for a phase change memory and a preparing method thereof. The phase change material for a phase change memory has a chemical formula of Sc 100-x-y-z Ge x Sb y Te z , wherein 0≤x≤60, 0≤y≤90, 0<z≤65, 0<100-x-y-z<100. The phase change material for a phase change memory according to the present invention is capable of repeatedly changing phases. The Sc 100-x-y-z Ge x Sb y Te z  has two different resistance value states, i.e., a high resistance state and a low resistance state, and a reversible transformation between the high resistance state and the low resistance state can be achieved by being applied a pulse electrical signal thereto, which satisfies basic requirements of a storage material for the phase change memory.

Claim (Index 9):
The method of preparing the phase change material for a phase change memory according to  claim 8 , wherein the method of preparing the phase change material for the phase change memory comprises obtaining a needed phase change material for a phase change memory by co-sputtering Sc simple substance target and Sb 2 Te 3  alloy target, Sc simple substance target and Sb 2 Te alloy target, or Sc simple substance target and Sb simple substance target as well as Te alloy target, wherein the Sc simple substance target uses a direct-current power source, and the Sb 2 Te 3  alloy target, the Sb 2 Te alloy target, the Sb simple substance target and the Te simple substance target use radio-frequency power sources.
