Impact of Surface Passivation on the Efficiency and High-speed Modulation of III-V GaAs/AlGaAs Nanopillar Array LEDs
Bejoys Jacob, João Azevedo, João Lourenço +3
III-V semiconductor nanolight sources with deep-subwavelength dimensions (1 m) are essential for miniaturized photonic devices such as nanoLEDs and nanolasers. However, the…

Electroluminescence in n-type GaAs unipolar nanoLEDs
Bejoys Jacob, João Azevedo, Jana B. Nieder +1
In this Letter, we report the observation of electroluminescence (EL) at around 866 nm from n-i-n unipolar (electron-transporting) III-V GaAs nanoLEDs. The devices consist of nanop…
