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 8):
A method of preparing the phase change material for a phase change memory according to  claim 1 , characterized in that: the method of preparing the phase change material for the phase change memory comprises preparing the phase change material for the phase change memory by using magnetron sputtering, chemical vapor deposition, atomic layer deposition, pulsed laser deposition, electron beam evaporation or electroplating according to different proportions of Sc, Ge, Sb and Te in the chemical formula of Sc 100-x-y-z Ge x Sb y Te z .
