Why do certain materials emit electrons with a very specific energy? This has been a mystery for decades - scientists have now found an answer. It is something quite common in physics: electrons leave ...

After nearly a century of probing the nature of tiny, ephemeral objects called excitons, researchers finally managed to image the structure, hinting at the true location of an electron. The findings ...

The red color denotes that the occurrence probability of valence electrons is 100 percent, the blue color means that no electrons exist in the area, and the green color means free electron-gas ...

Hanging around: this image shows where an electron is most likely to be found in an exciton. Yellow indicates high probability and blue low probability. The hole is located at the centre of the ...
