Recent advancements in computer technology have emerged from The Pennsylvania State University. Researchers have successfully built a computer using two-dimensional (2D) materials, marking milestone in the evolution of semiconductor technology. This development offers a potential alternative to traditional silicon-based systems, which have faced limitations as devices continue to shrink in size.
Complementary Metal-Oxide-Semiconductor (CMOS) technology is the foundation of modern electronic circuits. It is known for low power consumption and high component density. The recent shift towards 2D materials like molybdenum disulphide (MoS2) and tungsten diselenide (WSe2) aims to enhance the functionalities of these circuits. These materials are incredibly thin and scalable, making them suitable for future electronics.
Silicon has been the mainstay of electronics since the invention of the transistor in 1947. However, its effectiveness has plateaued. The miniaturisation of devices has led to issues like increased leakage current and power consumption. Researchers believe silicon has reached its limits in terms of size reduction and performance.
2D materials offer a promising alternative for future electronics. Their atomic-scale thickness allows for greater flexibility and efficiency. The Penn State team demonstrated that a computer built entirely from 2D materials can perform basic arithmetic functions. This breakthrough suggests that 2D materials could eventually replace silicon entirely.
Research on 2D materials is not limited to the United States. Institutions worldwide, including Fudan University in China, are exploring their potential. These efforts aim to support silicon initially and eventually transition away from it. The competitive landscape indicates a global race to innovate in semiconductor technology.
Despite the promising developments, several challenges remain. The operating speed of 25 kiloHertz achieved by the 2D computer is slower than that of silicon-based systems. Issues such as channel mobility, reliability, and scalability need to be addressed. Additionally, infrastructure for commercial translation of these technologies is still lacking in many regions.
The advancements in 2D materials could redefine the semiconductor landscape. They offer opportunities for improved performance and energy efficiency. The transition from silicon to 2D materials could lead to a new era of electronics, encouraging innovations that align with Moore’s Law in spirit, if not in practice.
