The modulation of a single-molecule electron source using light

https://phys.org/news/2023-03-modulation-single-molecule-electron-source.html

"single molecule and its molecular orbital miniaturize electron source... change molecular electron orbital passing through single-molecule emitter...vary emitter aperture's shape and emitted electron waves by exciting electrons with laser pulses... integration of ultrafast switches 6 orders of magnitude faster than in computer... integration of as many switches as desired without increase size... PEEM based attains spatial 0.3 nm also resolving single-molecule molecular orbitals... better computers and optics"
