Description

However, being extremely small and quick, electrons are difficult to control. Physicists around Dr. Peter Hommelhoff, head of the Max Planck Research Group “Ultrafast Quantum Optics” at the Max Planck Institute of Quantum Optics (Garching near Munich), have now demonstrated efficient guiding of slow electrons by applying a microwave voltage to electrodes fabricated on a planar substrate (Physical Review Letters, Advance online publication, 9 May 2011). This new technique of electron guiding – which resembles the guiding of light waves in optical fibres – promises a variety of applications, from guided matter-wave experiments to non-invasive electron microscopy
