Example Sentences

Scientists have used photoemission to confirm flat-band states in various 2D materials.

From Science Daily

In addition, these authors used a technique called angle-resolved photoemission spectroscopy to study the electronic structure at the material’s surface.

From Nature

As a result, streaking experiments have been unable to determine absolute photoemission delays — time differences between light absorption and electron ejection.

From Nature

Observation of Dirac cone band dispersions in FeSe thin films by photoemission spectroscopy.

From Nature

To do so, researchers typically carry out photoemission experiments, in which they shine a single photon of light onto a sample, that in turn kicks out a single electron.
