Will graphene transistor replace silicon?
• Very thin graphene layers can be used in electronic systems • These systems would manipulate electrons as waves DURING THE last three decades, significant research efforts have resulted in the size reduction of silicon-based semiconductor electronic devices in accordance with Moore’s law. Advances in microelectronic fabrication by lithography techniques have helped in miniaturazing electronic circuits at a fast rate for the past two decades. Size reduction But scientists and engineers predict that within the next decade the limit for the ultimate size reduction in silicon-based devices will be reached creating a dead end in the chip technology. The need for developing a substitute material to silicon has been realized a decade ago. The advancements in nanoscience and technology have given hope for the development of molecular electronic devices with fast response for a technological revolution.
