用第一性原理研究了氮化银的几种可能的结构。
This work reviewed the progress of research on the structure predicted , synthesis , characterization of carbon nitride materials in the past years , and discussed the present condition of research on their properties , especially electric conductivity rate .
Their solution was to take advantage of graphene 's electrical conductivity , by running a current through the mixture . This generated a temperature of 1650oc-more than enough to sinter the silicon nitride . The graphene , however , did not break down .
To eliminate the parasitic capacitance generated by the metallic molybdenum and tungsten films in the traditional bragg reflector structure , the tantalum nitride is proposed as a substitute for the high impedance material .
It is pointed out that the rare earths accelerate the diffusion of carbon and nitrogen atoms , and the formation of nitride , carbide and carbonitride through direct and indirect actions .
