Silicon and graphene are among the most important areas of research. Silicon is still the king of the semiconductor industry! On the other hand, graphene is the first two-dimensional material and has many unprecedented physical and chemical properties. The combination of silicon and carbon—or SiC—is yet another amazing material with a very bright future. Owing to its excellent thermal, mechanical, and semiconductive properties, SiC is a leading material for many strategic applications.
This article researches a very important question: is SiC the only possible composition of Si/C? Or could we play with the composition or dimensions of SixCy materials? View this paper
