Enhancement of the Electroluminescence from Amorphous Er-Doped Alsub.2Osub.3 Nanolaminate Films by Ysub.2Osub.3 Cladding Layers Using Atomic Layer Deposition
2023
Overview
Amorphous Al[sub.2]O[sub.3]-Y[sub.2]O[sub.3]:Er nanolaminate films are fabricated on silicon by atomic layer deposition, and ~1530 nm electroluminescence (EL) is obtained from the metal-oxide-semiconductor light-emitting devices based on these nanofilms. The introduction of Y[sub.2]O[sub.3] into Al[sub.2]O[sub.3] reduces the electric field for Er excitation and the EL performance is significantly enhanced, while the electron injection of devices and the radiative recombination of doped Er[sup.3+] ions are not impacted. The 0.2 nm Y[sub.2]O[sub.3] cladding layers for Er[sup.3+] ions increase the external quantum efficiency from ~3% to 8.7% and the power efficiency is increased by nearly one order of magnitude to 0.12%. The EL is ascribed to the impact excitation of Er[sup.3+] ions by hot electrons, which stem from Poole-Frenkel conduction mechanism under sufficient voltage within the Al[sub.2]O[sub.3]-Y[sub.2]O[sub.3] matrix.
