Tsukuba, Japan—Nanocarbon materials with pointed geometries, such as graphene and carbon nanotubes, are considered promising candidates as sources for field emission electrons. However, their ...

Physicists and engineers are familiar with costly high-energy electron-particle accelerators, and their mile-long structures needed to achieve mega-electron-volt (MeV) energy levels. But there’s a new ...

A collaborative team is attempting to combine electro-optical physics and a silicon MEMS structure to create a chip-size electron accelerator, in contrast to the mile-long versions in use today.
