Abstract :
We present tunnel junctions, employing buried semimetallic nanoparticles, to reduce intervalence-band absorption in mid-IR lasers. Proof-of-concept results demonstrate low resistance tunnel junctions with low p-type dopant concentrations, suitable for integration into GaSb-based diode lasers.
