Example Sentences

Because of these extreme conditions, widely used techniques like scanning tunneling spectroscopy and angle-resolved photoemission spectroscopy cannot be applied.

From Science Daily

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.

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.
