Quantum interference traps electron waves in metal for the first time

Researchers at Columbia University have trapped electron waves in a metal, Pd₅AlI₂, using quantum interference. The result, published in Science, comes a century after electrons were first described as waves.

• Experiment used the metal Pd₅AlI₂
• Electron waves were trapped via quantum interference
• Findings published in the journal Science
• Work builds on a century-old wave picture of electrons
