The End of the Silicon Era? Scientists Unveil World's First 2D Computer

Imagine a future where computers are not only smaller and more efficient but also more powerful and sustainable. That future is closer than you think, thanks to a team of scientists at Penn State who have developed the world's first 2D computer using atom-thin materials.

TL;DR
• Scientists at Penn State developed the world's first 2D computer using atom-thin materials.
• The computer is capable of performing basic operations and is a significant step towards creating ultra-efficient, miniaturized computing devices.
• The development of 2D material computers could lead to a new era in electronics, one that is more sustainable and powerful than ever before.

Summary
The development of the world's first 2D computer marks a significant milestone in the evolution of electronics. Researchers at Penn State have successfully created a functioning computer using two-dimensional materials, specifically molybdenum disulfide and tungsten diselenide, which are only one atom thick. This breakthrough paves the way for the creation of ultra-efficient, miniaturized computing devices.

Key insights from the development include:
• The 2D computer operates at low-supply voltages with minimal power consumption.
• It can perform simple logic operations at frequencies up to 25 kilohertz.
• The use of 2D materials maintains exceptional electronic properties at atomic thickness.
• The development of CMOS technology without silicon, combining large area grown molybdenum disulfide and tungsten diselenide transistors.

The 2D CMOS computer, also known as a one instruction set computer, is capable of performing basic operations. While its operating frequency is low compared to conventional silicon CMOS circuits, it still represents a significant advancement. The researchers used metal-organic chemical vapor deposition to grow large sheets of molybdenum disulfide and tungsten diselenide and fabricate over 1,000 of each type of transistor.

The field of 2D material computers is expected to develop gradually, but this achievement marks a leap forward compared to the trajectory of silicon technology, which has been under development for about 80 years. The research team, led by Saptarshi Das and Subir Ghosh, published their findings in Nature, with the paper titled 'A complementary two-dimensional material-based one instruction set computer'.

As we move forward in the development of 2D material computers, it's essential to consider the potential impact on our environment and our society. Can we harness the power of these new materials to create a more sustainable future?
