Photofield electron emission from an optical fiber nanotip
Sam Keramati, Ali Passian, Vineet Khullar +1
We demonstrate a nanotip electron source based on a graded index multimode silica optical fiber, tapered at one end to a radius of curvature r ~ 50 nm and coated with a thin film o…

Surface plasmon enhanced fast electron emission from metallised fibre optic nanotips
Sam Keramati, Ali Passian, Vineet Khullar +3
Physical mechanisms of electron emission from fibre optic nanotips, namely, tunnelling, multi-photon, and thermionic emission, either prevent fast switching or require intense lase…
