Description

A kind of room temperature ferromagnetic magnetic semiconductor material and application
Technical field
The present invention announces a kind of room temperature ferromagnetic magnetic semiconductor material and application, belongs to area of Spintronics.
Background technique
The present age and future are all the societies of information dominant force, the processing of information, transimission and storage will require unprecedented scale and Speed.Played the part of emphatically in information processing and transmission with large scale integrated circuit and high-frequency device that semiconductor material is support The role wanted.And semiconductor industry develops to today, the component number on VLSI chip presses Moore's Law not It is disconnected to improve, close to its limit.As the size of single transistor constantly reduces, channel length is from pervious micron order Nanoscale is developed to, the new problems such as leakage current increase, calorific value increase and parasitic capacitance effect can be not only brought, can also generate A series of quantum Interferences for being difficult to evade, the Performance And Reliability during influencing, make to further increase integrated level and chip Performance becomes difficult.Magnetic semiconductor material will be the active path to solve the above problems.Magnetic semiconductor not only has commonly The function of semiconductor, and it has been also equipped with the memory storage function of magnetic material, it can be used to change us and use semiconductor now The mode for the disc storage information that integrated circuit processing processing credit magnetic material is made into.That is magnetic semiconductor material can This two parts function to roll into one, device volume can be not only reduced, improves storage density, shortens call duration time, is accelerated The speed of service, and energy consumption can be greatly reduced.However only seldom magnetic semiconductor material has room-temperature ferromagnetic, this is very Working environment is limited greatly, so the research and development of room temperature ferromagnetic magnetic semiconductor material are extremely urgent.
