Note that the relatively large binding energies lead to incomplete ionization of the dopants in 4H- and 6H-SiC that will affect the device behavior within a wide range of operation conditions. Bismuth (Bi)-doped photonic materials, which exhibit broadband near-infrared (NIR) luminescence (1000–1600 nm), are evolving into interesting gain media. However, the traditional methods have shown their limitations in enhancing Bi NIR emission, especially in the microregion. Consequently, the typical NIR emission has seldom been achieved in Bi-doped waveguides, which highly ... ionization energy - the amount of energy needed to remove an electron from a specific atom or ion in its ground state and gas phase.
