The temperature dependant electrical properties of InSbN alloys fabricated by directly nitrogen ion implanted into InSb substrate are investigated using Hall effect measurement. Intrinsic behavior is observed in the high temperature range (180-300 K). Higher nitrogen doping level and annealing temperature will result in lower electron carrier concentration. Phonon scattering dominates.
We study the optical gain and alpha factor of InAs/InAlGaAs quantum-dash lasers on InP substrate after being subjected to the postgrowth intermixing process. The intermixing was achieved using dielectric capping process that involves the deposition of dielectric film and subsequent rapid thermal annealing. Compared to the un-intermixed laser, we found that the intermixed lasers with a 93 nm bandgap...
