The deep-level structures and the carrier-emission processes are precisely analyzed. For the crystal-field-split levels of Fe/sup 2+/:/sup 5/E and /sup 5/T/sub 2/, the fundamental transitions of /sup 5/E-/spl Gamma//sub 1/, /spl Gamma//sub 15/-/sup 5/E in InP:Fe, and /spl Gamma//sub 15/-/sup 5/E, /spl Gamma//sub 15/-/sup 5/T/sub 2/ in In/sub x/Ga/sub 1-x/P:Fe are adequately described by the Lucovsky-model calculation. The optical thresholds and the crystal-field-split energies are determined accurately. The small difference between the optical and thermal energies indicates that the Fe acceptor level is perturbed weakly by the lattice vibration in the InP and In/sub x/Ga/sub 1-x/P. Nonexponential photocapacitance transient is observed in the In/sub x/Ga/sub 1-x/P:Fe for the alloying effects.","PeriodicalId":213868,"journal":{"name":"Conference Proceedings.

So far, room temperature operations of 1.3 /spl mu/m GaInNAs/GaAs edge emitting lasers grown by either gas source MBE or MOCVD have been demonstrated. However, the degradation of crystal qualities with increasing the nitrogen composition is a remaining problem. The origin for the deterioration is still unclear. It is essential to find the origin and to improve the quality of GaInNAs for realizing high performance long wavelength GaInNAs lasers. In this work, we present the composition dependence of emission characteristics of highly strained GaInNAs quantum well lasers, including the carrier lifetime, the spontaneous emission efficiency and the threshold current density. A prospect of long wavelength GaInNAs VCSELs for high speed LANs is also discussed.","PeriodicalId":213868,"journal":{"name":"Conference Proceedings.

We have found that an unrecoverable increase of emitter-collector reverse current (I/sub CEO/) occurs during reverse-bias B-C junction stress, which is mainly due to the increase of the B-C junction leakage current. Furthermore, the hot carrier induced damage during the B-C bias stress does not only occur at the B-C junction but also at the B-E junction region. This subsequently causes the degradation of the device current gain (/spl beta/). We also show the dependence of the device degradation on different stress bias voltages.","PeriodicalId":213868,"journal":{"name":"Conference Proceedings.

The V-shape is preserved during InAlAs barrier layer growth due to a suppressed migration of In atoms under As/sub 2/ flux.

In this paper we report on drastic improvements of the MOBILE concept addressing the major restrictions: trade-off between output driving capability, number of inputs and additional current for the parallel input branches, critical design criteria for two independent technologies: HFET (threshold voltage, lateral current density) and RTD (device area, vertical current density).","PeriodicalId":213868,"journal":{"name":"Conference Proceedings.
