valence and conduction bands造句

例句与造句

1. The band gap of valence and conduction bands overlap.
2. Technically, the encoding effect proceeds by the creation of a population inversion between the valence and conduction bands, with the resulting creation of plasmons.
3. In the type II configuration, the valence and conduction band edge of the core are both lower or higher than the band edges of the shell.
4. In contrast, a material with a large band gap is an conductors, the valence and conduction bands may overlap, so they may not have a band gap.
5. The method makes use of electrons trapped between the valence and conduction bands in the crystalline structure of certain types of matter ( such as quartz, feldspar, and aluminium oxide ).
6. It's difficult to find valence and conduction bands in a sentence. 用valence and conduction bands造句挺难的
7. When an avalanche occurs, the PN junction is flooded with charge carriers and trap levels between the valence and conduction band become occupied to a degree that is much greater than that expected in a thermal-equilibrium distribution of charge carriers.
8. In graphs of the electronic band structure of solids, the band gap generally refers to the energy difference ( in electron volts ) between the top of the valence band and the bottom of the conduction band in conductors either have very small band gaps or none, because the valence and conduction bands overlap.
9. Recombination can occur by direct encounter with a majority carrier, annihilating both carriers, or through a LED recombination of electrons and holes is accompanied by emission of light of a wavelength related to the energy gap between valence and conduction bands, so the diode converts a portion of the forward current into light.
