| 11. | This is the basis of the optical band gap in a photonic crystal.
|
| 12. | Thus we observe an increase in the apparent band gap.
|
| 13. | There is a phononic band gap within a range of " normalized frequencies ".
|
| 14. | This means that the semiconductors used have dissimilar band gaps.
|
| 15. | Owing to their direct band gap, TMDC monolayers are promising materials for optoelectronics applications.
|
| 16. | The apparent effects are : band gap reduction, valence band splitting, and optical anisotropy.
|
| 17. | In conductors, there is no band gap, so the electrons are free to conduct.
|
| 18. | Different from silicon with an indirect bandgap, perovskite material has a direct band gap.
|
| 19. | In insulators, the band gap is " large ", and there is no conduction.
|
| 20. | MOS Band gap references use lateral ( poor ) bipolar transistors for their functioning.
