Ultrafast Electron camera

Experiment on ultrafast electron diffraction (UED), has been done which has proven to be one of the world’s fastest ‘electron cameras’ that can take snapshots of a three-atom-thick layer material while it wrinkles in response to a laser pulse initiated over it. Once fully understood these dynamic ultra ripple system could provide hopes for a much better next generation solar cells, electronics and catalysts.

latest research done by  Department of Energy’s SLAC National Accelerator Laboratory and Stanford University provides a glance over how individual atoms move in trillionths of a second to form wrinkles on a three-atom-thick material. This has proven to be world’s speediest brand new “electron camera,” which could result in fastest growing technology of developing efficient solar cells, fast and flexible electronics and high-performance chemical catalysts.

“Combined with theoretical calculations, these data show how the light pulses generate wrinkles that have large amplitudes — more than 15 percent of the layer’s thickness — and develop extremely quickly, in about a trillionth of a second. This is the first time someone has visualized these ultrafast atomic motions,” Lindenberg said.
