How to use in-sentence of “band gap”:
– The band gap energy of semiconductors tends to decrease with increasing temperature.
– The band gap determines what portion of the solar spectrum a photovoltaic cell absorbs.
– In a regular semiconductor crystal, the band gap is fixed owing to continuous energy states.
– A semiconductor is a material with a small but nonzero band gap which behaves as an insulator at absolute zero temperature but allows heat to excite electrons enough to jump into its conduction band at temperatures which are below its melting point.
– Band gap engineering is the process of controlling or altering the band gap of a material by controlling the composition of certain semiconductor alloys, such as GaAlAs, InGaAs, and InAlAs.
– In graphs of the electronic band structure of solids, the band gap is the energy difference between the top of the valence band and the bottom of the conduction band.
– In a quantum dot crystal, the band gap is size dependent and can be altered to produce a range of energies between the valence band and conduction band.
