Researchers from Georgia Tech University in Atlanta have announced a groundbreaking discovery – they have developed the first functional semiconductor based on graphene. This new material, known as Semiconductor Epitaxial Graphene (SEC), promises to revolutionize electronics by offering significantly higher speeds and capabilities, particularly in the field of computers.

The technique used by the researchers to obtain this material is simple and has been known for 50 years – heating silicon carbide at high temperatures. As a result, silicon vaporizes from the surface and graphene forms on it. This method is crucial for achieving consistent results and high electron mobility.

One of the great advantages of graphene is that it acts as a semiconductor with much higher electron mobility compared to traditional materials such as silicon. Transistors based on this material could operate at incredible speeds in the terahertz range, which is a huge leap from current practical product speeds.

In addition, researchers highlight graphene’s potential for quantum computing. When this material is used at low temperatures, electrons exhibit wave-like quantum-mechanical properties that are not available in silicon. These properties open up possibilities for a completely new approach to electronics.

While researchers acknowledge that their discovery will not be immediately applicable in its current form, they continue to experiment with new materials such as boron nitride to protect graphene and increase its compatibility with conventional semiconductor manufacturing lines.

The development of this technology will require time, but the amount of work invested in it will be crucial for faster implementation. Industry support will be of great importance in achieving further progress and realizing all the possibilities that graphene chips bring to electronics.
