Abstract

The invention discloses a preparation process of a semi-metallic surface based on SrC. The preparation process comprises the following steps: step 1, constructing a crystal structure of table-salt-type SrC, and optimizing the lattice structure of the table-salt-type SrC; step 2, calculating the state density of the SrC and carrying out analyzing under an equilibrium lattice constant aeq; step 3, constructing two surface structures of the direction of SrC(111) and carrying out optimization; step 4, calculating the state density of the surface structure subjected to the calculation and optimization, and carrying out analyzing; and step 5, obtaining a surface structure with a semi-metallic characteristic through analyzing and comparing. With the adoption of the scheme provided by the invention, a plurality of advantages of the spin electronic devices can be best exerted, and the preparation process has good market application value.

Description

technical field [0001] The invention relates to a preparation process based on SrC surface semi-metallicity. Background technique [0002] Injecting highly efficient spin-polarized currents into semiconductors has aroused great interest in the field of spintronic devices in recent years. However, the mechanism of this spin-polarized injection is still not fully understood. One main reason lies in the large impedance mismatch between the spin injection source and the semiconductor substrate during the lengthy quantum transport process. Semi-metallic ferromagnets, which exhibit metallicity in one spin direction and semiconducting or insulating properties in the other, resulting in 100% spin polarization near the Fermi surface, are considered ideal spin Injection source. [0003] Nowadays, people have found that many kinds of materials have the above-mentioned half-metallic ferromagnetism. According to the different reasons for their semi-metallic properties, semi-metallic m...
