A major obstacle may be standing in the way of the next generation of ultra-tiny computer chips. Researchers discovered that many promising 2D materials lose their advantages because an invisible atomic-scale gap forms when they are combined with insulating layers. That tiny gap weakens electronic performance and could prevent further miniaturization. The team says new […]
Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power. By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide bandwidth. Its efficiency and small size mean it could run on batteries and be integrated into consumer electronics. This breakthrough […]
Researchers have, for the first time, directly visualized how electronic patterns known as charge density waves evolve across a phase transition. Using cutting-edge microscopy, they found these patterns form unevenly, breaking into patches influenced by tiny structural distortions. Unexpectedly, small pockets of order persist even above the transition temperature. This reveals that electronic order fades […]
Researchers have visualized atoms in motion just before a radiation-driven decay process occurs, revealing a surprisingly dynamic scene. Instead of remaining fixed, the atoms roam and rearrange, directly influencing how and when the decay unfolds. This “atomic movie” shows that structure and motion play a central role in radiation damage mechanisms. The findings could improve […]
MIT physicists have built a powerful new microscope that uses terahertz light to uncover hidden quantum motions inside superconductors. By compressing this normally unwieldy light into a tiny region, they were able to observe electrons moving together in a frictionless, wave-like state for the first time. This discovery opens a new window into how superconductors […]
Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbon–carbon bonds under mild conditions. This could make drug discovery faster and more […]
