Silicon carbide, also known as SiC material, is a relatively new type of semiconductor material. Its properties are similar to silicon and it is used for devices where high temperatures are required such as in power electronics, heating elements and other components that need to withstand high heat levels.
SiC has certain advantages over silicon such as higher thermal conductivity and a lower dielectric constant. These advantages make it possible for SiC to reach higher operating temperatures than silicon-based components which in turn means that devices can be smaller because less heat needs to be dissipated from them. SiC can take advantage of its low thermal conductivity by using an external coolant or heatsink instead of cooling fluid internally.
Because SiC’s operation voltage is up to 20% higher than silicon’s and its breakdown voltage level is twice that of silicon, this makes SiC particularly suitable for switching applications in power electronics. One disadvantage with using SiC materials though is that they have a lower resistivity than their silicon counterparts; this might not be desirable depending on the application. Other disadvantages are a higher cost per watt (compared to silicon) and more difficult fabrication process due to the complicated crystalline structure of SiC. A good example of how this material is being used today would be in light emitting diodes (LED) due to its ability to emit blue light at very high temperature levels.
The current use of SiC technology is mainly limited to electronic industry. However, recent studies show that SiC may become widespread in other industries such as construction, automotive and biomedical engineering too. In some ways, SiC could even replace silicon. For example, if someone wants to develop a phone without any metal components, then SiC could be used as the base material for these parts because it does not corrode like metals do. Similarly, in medical engineering if someone wants to create biochips that require high temperature then this is something that should be done using SiC material rather than silicon based materials since the former will operate reliably at these temperatures whereas the latter won’t. As well as replacing silicon in some cases and expanding into new industries, there are currently many projects underway aiming to improve the efficiency of SiC so it becomes easier to manufacture.
