This effect, known as photoemission, was explained by Albert Einstein more than hundred years ago.
This effect is known as photoemission and was explained by Einstein more than hundred years ago.
I also predicted the so-called large pseudogap in the cuprates that was eventually discovered by Prof. Shen in photoemission from samples in extreme underdoping.
In angle-resolved photoemission experiments and transport studies on a cuprate material that exhibits striped electronic inhomogeneity, scientists for years observed that superconductivity is heavily affected by the nanoscale features and in some respect even optimized.
AR65view is a free and open source program built to analyze and manipulate the photoemission data measured by the ARPES experiments AR65 and WESPHOA.

They therefore estimate the influence of the electrons which are not themselves ejected from the atom in the photoemission with an average value.
Since the discovery of photoemission more than one hundred years ago this has also applied to the question of how quickly a light beam ejects an electron from an atom, because it was clear that the process would in any case be much shorter than even the most accurate methods could measure.
Austria and Saudi Arabia: "We discovered that there is a delay in the photoemission."
The assumption so far has been that, during photoemission, electrons immediately shoot out when the light pulse impinges on the material.
