Electrons become fractions of themselves in graphene, study finds

The electron is the basic unit of electricity, as it carries a single negative charge. This is what we’re taught in high school physics, and it is overwhelmingly the case in most materials in nature. But in very special states of matter, electrons can splinter into...

MIT physicists turn pencil lead into “gold”

MIT physicists have metaphorically turned graphite, or pencil lead, into gold by isolating five ultrathin flakes stacked in a specific order. The resulting material can then be tuned to exhibit three important properties never before seen in natural graphite. “It is...

From a five-layer graphene sandwich, a rare electronic state emerges

Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair. Under a microscope, the material resembles a chicken-wire...

Physicists coax superconductivity and more from quasicrystals

In research that could jump-start interest into an enigmatic class of materials known as quasicrystals, MIT scientists and colleagues have discovered a relatively simple, flexible way to create new atomically thin versions that can be tuned for important phenomena. In...

Energy-harvesting design aims to turn high-frequency electromagnetic waves into usable power

Note: This story was updated on Dec. 18 to clarify that Wi-Fi signals are in the microwave frequency range, not terahertz, as originally reported. The device described in the article would convert energy in a range of electromagnetic frequencies, including terahertz...

Pablo Jarillo-Herrero delivers 2022 Dresselhaus Lecture on the magic of moiré quantum matter

“We have barely scratched the surface of the moiré quantum matter universe,” said Pablo Jarillo-Herrero at the 2022 Mildred S. Dresselhaus Lecture. The Cecil and Ida Green Professor of Physics at MIT, Jarillo-Herrero is at the forefront of the scientific exploration...
