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 nanopillars with top diameter 166 nm, arranged in a 10x10 pillar array. Hole generation through impact ionization and Zener tunnelling is achieved by incorporating an AlAs/GaAs/AlAs double-barrier quantum well within epilayer structure diode. Time-resolved EL measurements reveal decay lifetimes larger than 300 ps, allowing...
Abstract A proof‐of‐principle device for axial high‐resolution operation that combines a deoxyribonucleic acid (DNA) origami with functionalized graphene layer is presented, analyzed by nanoscopy. Along the DNA structure, ATTO‐488 fluorophores are bound at specific distances from graphene, where fluorescence lifetime values expected due to nearfield energy transfer processes. These characterized Fluorescence Lifetime Imaging Microscopy (FLIM). Through modulation of electrostatic potential...
