41. The Airy function includes a " tail " which extends into the classically forbidden band gap . 42. 9 . Optical Band gap on wurtzite Zinc Sulphide nanocrystallites doped with lanthanum ions ( Proce. 43. The Fermi level of an intrinsic semiconductor is exactly in the middle of the band gap . 44. Variable index liquids or liquid crystals injected into the network alter the ratio and band gap . 45. The " apparent " band gap of a semiconductor can be measured using transmission / reflection spectroscopy. 46. Other experiments have demonstrated that the formation of perchlorate is associated with wide band gap semiconducting oxides. 47. The size of this energy band gap serves as an arbitrary dividing line ( roughly 4 insulators. 48. The pentagons could introduce a band gap . 49. One approach is to think of semiconductors as a type of insulator with a narrow band gap . 50. They were the first to demonstrate the existence of photonic band gaps ( " PBGs " ).
