Since its discovery, graphene is a material that researchers have been hoping for. Computers using graphene will be much faster and more powerful than the devices we use today.
Graphene is a 2D version of graphite. Since its discovery in 2004, this single atomic structure has attracted the attention of engineers, metallurgists and researchers. There are many reasons for this interest in graphene. This material, which is 100-300 times stronger than steel, is much more advanced than copper in terms of electrical current transmission. Therefore, graphene stands out as the strongest, thinnest and most reliable electric conductor material by far. Graphene is an important alternative raw material for the billions of chips and electronic components that we use in the modern world.
Although copper has been used to make interconnections for more than twenty years, this metal is far from ideal. Copper is a material that has structurally physical limits and is impossible to use on a nanoscale. As copper gets thinner, its resistance increases. The higher the resistance, the more difficult the current is. This means slowing down computers.
The main problem of graphene is that we do not know how to use this substance to make microcomponents for commercial purposes. Kaustav Banerjee, an Electronics and Computer Engineer at the University of California, says that no matter what parts are involved, we need to find a way to secure graphene to silicon sheets in order to advance the industry.
Research in Banerjee’s laboratory has finally revealed the way to produce high-conductivity, nano-scale, reinforced multilayer graphene (DMG) interconnects, suitable for integrated circuits and in large quantities.
Banerjee developed a special method. In this method, solid state fusion is carried out with the help of pressure. Thus, graphene can be included in CMOS production, which is used as standard.
In this method, graphite powder is poured into a nickel strip of ideal thickness and pressure is applied at 300 degrees. By controlling this system, Barenjee and his team were able to produce graphene with the desired optimal thickness. Thus, faster, powerful, small, lightweight, flexible, reliable and cost-effective computers will be available.
