Electroluminescence on-off ratio control of n-i-n GaAs/AlGaAs-based resonant tunneling structures

E. R. Cardozo de Oliveira, A. Pfenning, E. D. Guarin +7

We explore the nature of the electroluminescence (EL) emission of purely n-doped GaAs/AlGaAs resonant tunneling diodes (RTDs) and the EL evolution with voltage. A singular feature…
