Abstract: We found that the length of the Fermi arc decreases with increasing out - of - plane disorder by performing angle resolved photoemission spectroscopy (ARPES) measurements in the superconducting state of optimally doped R = La and Eu samples of Bi2Sr2 − xRxCuOy. (arxiv.org)
Since out - of - plane disorder stabilizes the antinodal pseudogap as was shown in our previous study of the normal state, the present results... ▽ More We found that the length of the Fermi arc decreases with increasing out - of - plane disorder by performing angle resolved photoemission spectroscopy (ARPES) measurements in the superconducting state of optimally doped R = La and Eu samples of Bi2Sr2 − xRxCuOy.

Even more than 100 years after Einstein's explanation of photoemission the process of electron emission from a solid material upon illumination with light still poses challenging surprises. (sciencedaily.com)
