Researchers at the SLAC National Accelerator Laboratory have created a high-energy, ultrashort, ultrahigh current petawatt peak power electron beam ... ever before,” lead author Claudio Emma ...

Measuring the ultra-short electron bunches was also a challenge. “These are typically so intense that if you intercept them with, for example, scintillating screens (a typical technique used in ...

The lead carbanion layer was responsible for reducing defects at the interface bewteen the perovskite layer and the electron transport ... voltage of 1.17 V, a short-circuit current density ...
