Bandgap带隙
A bandgap is the energy range between the valence band and the conduction band in a semiconductor material, where no electronic states are available for carriers. In semiconductor documentation, the term determines light absorption and emission wavelengths, intrinsic carrier concentration, junction built-in voltage, and the temperature dependence of device behavior, and it is a key physical parameter in materials comparisons.

Where this term appears
In localization work, the term bandgap appears in material property tables, photodetector and LED datasheets, sensor documentation, and semiconductor physics training content. It also occurs in simulation model descriptions, process integration documents, and academic abstracts where silicon, germanium, and compound semiconductor behavior is compared across different temperature and doping ranges.
Translation checks
A common error is incorrectly translating bandgap inconsistently as “带隙宽度,” “禁带宽度,” or “能隙,” or confusing it with a discrete energy level rather than an energy range. In optoelectronic texts, ambiguous wording around wavelength, voltage, and material temperature performance can distort claims about detection range, emission color, and device operating limits.
Keep the term aligned across your files
Technical terms need checking against the source, approved product terminology and related specifications. Keep units, parameter conditions and document versions aligned across the file set.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
