WebApr 13, 2024 · However, a mismatch was found to exist between the AlN and sapphire in the lattice constant and thermal expansion coefficient [16,17], resulting in an AlN film with a very high TDD, usually between 10 9 and 10 10 cm −2. Due to the nonradiative recombination of carriers at the dislocation, a high TDD significantly reduces the IQE of multiple ... WebMar 13, 2024 · We propose the use of an n-doped periodic AlN/GaN quantum cascade structure for the optical up-conversion of multiple near-infrared (near-IR) photons into deep-ultraviolet (deep-UV) radiation. Without applying an external bias voltage, the active region of such a device will (similar to an un-biased quantum cascade laser) resemble a …
