N型4H-SiC表面改性及性能研究

Study on Surface Modification and Characterization Of N-type 4H-SiC

研究了在N型4H-SiC的表面上引入炔基来提高表面的固定密度和稳定性的方法。炔基的引入可以为DNA探针在碳化硅表面固定做好铺垫,从而改善碳化硅表面生物活性,为制备碳化硅基生物传感器具有一定指导意义。

The method to improve the fixed density and stability of N type 4H-SiC surface by introducing alkynes was studied.The introduction of alkynes can pave the way for the fixation of DNA probes on the surface of SiC,so as to improve the biological activity on the surface of SiC,which has certain guiding significance for the preparation of silicon carbide based biosensors.
