Researchers anticipate that this tech could lead to breakthroughs in fields like physics, chemistry, bioengineering, and materials science.
The researchers generated a single attosecond electron pulse to capture an electron in a fixed state, matching the speed at which electrons move.Researchers at the University of Arizona have created the world’s fastest electron microscope, a remarkable device capable of capturing freeze-frame images of moving electrons.
Unlike traditional microscopes, where image quality depends on the camera’s shutter speed, the resolution in these advanced transmission electron microscopes is determined by the duration of the electron pulses.Earlier ultrafast electron microscopes operated by emitting a series of electron pulses at speeds measured in attoseconds—one quintillionth of a second.
By meticulously synchronizing these two pulses, researchers can precisely control when the electron pulses interact with the sample, allowing them to capture and observe ultrafast processes at the atomic level.
