According to foreign media reports, IBM researchers said on Thursday that they have used grapheme materials to design high-speed circuit boards. Graphene is an ultra-thin material that is widely used in high-bandwidth communications and a new generation of low-cost smart phones and TV screens.
As a special form of graphite, graphene mainly consists of a layer of carbon atoms in a honeycomb lattice structure and can be used to increase the conduction velocity.
The United States "Science" magazine published the results of IBM's research. In the circuit board design, researchers built a wideband mixer in a silicon chip. The circuit board is widely used in the design of communication equipment, the role is to switch signals between different frequency bands. In previous studies, IBM had developed a single graphene transistor, but it has never developed a complete circuit board.
However, this new material can not replace the traditional CMOS transistor, which is currently the material commonly used in microprocessors and computer memory in consumer electronics systems. Graphene is not yet fully equipped with the physical characteristics of semiconductor materials, so it is difficult to achieve the working mechanism of the traditional transistor.
