Low-Defect Quantum Dot Lasers Directly Grown on Silicon Exhibiting Low Threshold Current and High Output Power at Elevated Temperatures
Konstantinos Papatryfonos, Jean-Christophe Girard, Mingchu Tang +6
The direct growth of III-V materials on silicon is a key enabler for developing monolithically integrated lasers, offering substantial potential for ultra-dense photonic integratio…

Atomic scale visualization of the p-d hybridization in III-V semiconductors doped with transition metal impurities
K. Badiane, G. Rodary, M. Amato +4
p-d hybridization of transition metal impurities in a semiconductor host is the mechanism that couples valence-band electrons and localized spins. We use scanning tunneling microsc…
