Photoelectric effect - Wikipedia
The photoelectric effect is the emission of electrons from a material caused by electromagnetic radiation such as ultraviolet light. Electrons emitted in this manner are called photoelectrons.
6.3: Photoelectric Effect - Physics LibreTexts
When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength (or equivalently, above a threshold frequency), the incident radiation is absorbed and the exposed surface emits electrons. This phenomenon is known as the photoelectric effect.
Photoelectric effect | Definition, Examples, & Applications
2024年10月25日 · photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.
Photoemission spectroscopy - Wikipedia
Photoemission spectroscopy (PES), also known as photoelectron spectroscopy, [1] refers to energy measurement of electrons emitted from solids, gases or liquids by the photoelectric effect, in order to determine the binding energies of electrons in the substance.
Photo Electrons: Definition, Properties, and Applications
2023年6月18日 · A photoelectron is defined as an electron emitted from a material when it absorbs light energy. This emission process is called the photoelectric effect and it provides key evidence for the quantum nature of light and matter.
Photoelectron - an overview | ScienceDirect Topics
A photoelectron is an electron emitted from a material in response to the absorption of photons, carrying specific information about the chemical, magnetic, and electronic properties of the material at a lateral resolution better than 100 nm.
