This could be explained by the fact that the non-centrosymmetric crystal structure of 3C-SiC increases its polarity due to charged structural defects in the lateral direction such as domain boundaries, threading dislocations, etc.

Introduction
The ferrites that are based on the structure of Fe2O3 have a crystallization of the spinel type, and this can be described as the AB2O4, where A and B are, respectively, the cations occupying the tetrahedral sites and octraédricas unit cell [1].

Because of their high melting points exceeding 3000 oC, retained strength and thermal stability, these materials can be potential candidates for several space application, such as thermal protective structures for leading-edge parts on hypersonic flight and rocket propulsion [1,2,3].

Due to the limitation of the resolution of transmission electron microscope, the structure of organic molecules can not be observed, so the research on the interface between NCs and organic molecular can be conducted only through some indirect methods.
