WebIn solid-state physics, a band gap, also called a bandgap or energy gap, is an energy range in a solid where no electronic states exist. In graphs of the electronic band structure of solids, the band gap refers to the energy difference (often expressed in electronvolts) between the top of the valence band and the bottom of the conduction band in insulators … Web16 apr. 2024 · Between these types of smoke detectors, you must understand that each has its strengths. Photoelectric smoke detectors tend to react faster with combustions that occur on solid objects while Ionization smoke detectors tend to react faster with fires that occur on the gas phase. Because fire occurrence is not predictable, it is difficult to plan ...
