The observation of free electron-light interactions was facilitated by the discovery of a technique known as photon-induced near-field electron microscopy (PINEM).

We believe that the observation of the photon-induced near-field effect in ultrafast electron microscopy demonstrates the potential for many applications, including those of direct space-time ...

Einstein's photoelectric effect: The time it takes for an electron to be released Researchers examine photoelectric effect with the aid of a COLTRIMS reaction microscope Date: February 10, 2022 ...

When a photon comes in, it hits the marble (or electron), giving it enough energy to escape from the well. This explains the behavior of light striking metal surfaces.

The goal of this project is to reveal the guiding principle for enhancing the bulk photovoltaic effect and develop new materials for high-efficiency photon-to-electron conversion.

Two independent teams of physicists are the first to have entangled a single photon with a single electron spin held in a quantum dot. Thanks to the ease with which quantum dots can be fabricated and ...

Until recently subwavelength optics laid great hopes on the effects related to interactions of light with the, so-called, plasmons -- collective oscillations of free electron gas in metals.

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly ...

Despite the popularity of Einstein's theories of relativity and his musings on black holes, Einstein's Nobel Prize in physics was actually awarded for his discovery of the photoelectric effect ...

Moreover, the only measurement we can ever make for a photon is inherently destructive to the photon; detecting a photon requires an interaction with another quanta, like an electron, which then ...
