Physicists create five-lane superhighway for electrons

MIT physicists and colleagues have created a five-lane superhighway for electrons that could allow ultra-efficient electronics and more. The work, reported in the May 10 issue of Science, is one of several important discoveries by the same team over the past year...

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...
In nanotube science, is boron nitride the new carbon?

In nanotube science, is boron nitride the new carbon?

Engineers at MIT and the University of Tokyo have produced centimeter-scale structures, large enough for the eye to see, that are packed with hundreds of billions of hollow aligned fibers, or nanotubes, made from hexagonal boron nitride. Hexagonal boron nitride, or...

Physicists find direct evidence of strong electron correlation in a 2D material for the first time

In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that allows electrons to flow with zero resistance. These...

Gene Dresselhaus, influential research scientist in solid-state physics, dies at 91

Gene Dresselhaus, a longtime research physicist at MIT’s Lincoln Laboratory and later the Francis Bitter Magnet Laboratory at MIT (now part of the MIT Plasma Science and Fusion Center), died peacefully at his home in California on Sept. 29. He was 91. Dresselhaus was...
