Explained | How Singapore scientists cracked the code for 'cooler' & more energy-efficient gadgets
Physicists at the National University of Singapore have achieved a groundbreaking advancement in the field of 2D spintronics, particularly in graphene, with potential implications for low-power electronics. Here's what it means for everyday consumers like you and me, and why we should care.

The Challenge: Devices getting too hot

We are all familiar with our gadgets heating up occasionally — this happens because as electricity flows through these devices, it creates heat. Scientists have been trying to find ways to make devices more energy-efficient and less prone to overheating, which has long-term benefits for us such as lower electricity bills, and 'cooler' devices.
Spintronics: The cool alternative

According to a piece published by the scientific website SciTechDaily, Singaporean scientists — instead of relying on the flow of electricity (charge) — looked at something called 'spin' to power devices. If successful, this could mean devices that use less power and operate much faster without getting too hot. They've named this 'spintronics.' Spintronics is a branch of nanotechnology that exploits the spin of electrons, rather than their charge, to store and manipulate information.
Graphene: The super-thin hero material

As part of this quest, scientists have used graphene, a two-dimensional material made of carbon atoms arranged in a hexagonal lattice. It has remarkable properties such as high strength, electrical conductivity, and flexibility. It is considered a potential material for many applications in nanotechnology, electronics, biomedicine, and more. Even though graphene doesn't naturally have the spin properties needed, scientists have found ways to make it behave the way they want.
The Big Discovery: Controlling spin in graphene

Led by Professor Ariando and his team, researchers developed spintronics to directly measure and control the way electrons spin in magnetic graphene. It's like they found a way to steer a car just by looking at its wheels — a breakthrough in understanding and manipulating how electrons behave.
Tuning the Spin Properties: Making graphene adaptable
The scientists figured out how to adjust the spin properties of graphene over a wide range. It's like having a knob that lets you control how fast or slow something spins. This adaptability opens the door to creating more efficient electronics.
How They Did It: Fun experiments and smart computer learning
To prove their ideas, the researchers did some experiments, like stacking graphene on top of a special magnetic material. They used a trick called the Landau fan shift — a phenomenon that occurs when a two-dimensional material, such as graphene in this instance, is placed near a magnetic material. It causes the energy levels of the electrons in the material to split according to their spin orientation — to measure the spin properties. They also collaborated with computer experts to analyse their data using machine learning, a bit like having a computer learn and improve from examples.
Practical implications for average consumers
1. Energy efficiency: Devices built using this technology could significantly reduce energy consumption, leading to longer battery life for smartphones, laptops, and other gadgets.
2. Performance: The ultrafast speed promised by this breakthrough could result in quicker response times for applications, smoother multitasking, and overall improved performance in electronic devices.
4. Extended device lifespan: The reduction in joule heating may contribute to increased durability and longer lifespans for electronic components, potentially lowering the frequency of replacements or repairs.
5. Next-gen electronics: As this technology develops, it may pave the way for a new generation of electronic devices with enhanced capabilities and efficiency, influencing various industries beyond personal electronics.
The future of electronics

The researchers aren't stopping here. They want to explore further, using these findings to create electronics that work even better at room temperature. The ultimate goal is to apply this knowledge to develop new types of electronic circuits and memory devices. Imagine a future where your devices are not just powerful but also energy-efficient, making your everyday tech experience even smoother.
In a nutshell, this breakthrough is like finding a superpower for our electronic devices — making them not only smarter but also more efficient and reliable.
