An international research group successfully measured, with a nanometer resolution, the depth of PN junctions varied in a Si ...

Compared with hot electrons, hot holes show higher density below the Fermi level, the longer mean free path arising under the lower electron–electron and electron–phonon scatterings, a lower barrier ...

We finally know what brought light to the dark and formless void of the early Universe. According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the ...
