way to measure the brevity of these electron bursts. To deal with this hurdle, the team developed a new type of camera that can take snapshots of the electrons during the short time the laser is pushing [...] pushing them out from the nanotip and into the vacuum. ”The trick was to use a second, very weak, light flash” said Dr. Hee-Yong Kim, the leading author of the new study. “This second laser flash can gently [...] computers or other electronic gadgets slow or fast? It is the time it takes electrons, one of the tiniest particles in the microcosm, to stream out from the minute leads inside transistors of electronic microchips
