Assertion: germanium's electron | /r/HasProperty | excited
Facets:
value: from the filled valence band
type: OTHER
Source sentences:
text: Similarly, doping silicon with a group 13 element such as boron, aluminium, or gallium results in the introduction of acceptor levels that trap electrons that may be excited from the filled valence band, creating a p-type semiconductor.
text: In some of the germanium nanocrystals, the photons cause electrons to be excited, and thus form an electron-hole (e-h) pair.
text: The excess energy of the electron – the ‘kinetic’ energy of the electron which is excited high up in the conduction band – is sufficient to create a second e-h pair in the same nanocrystal.
