Abstract: Polymer-derived silicon carbonitrides (SiCN) ceramics are wide band gap semiconductors with excellent properties at high temperature, which are attributed to their unique nanostructure. As experiments still have problems to study the nano-structure of SiCN, in this work, molecular dynamics simulations were conducted to study the nano-structure of amorphous SiCN with different carbon contents. The results of bonds distribution, interfacial structure and Si-centred tetrahedrons give an insight on how composition influences the structures of nano-domain and domains interface.
