Published 1996Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: The spectral electroluminescence characteristics of broad-area (Al)GaAs/In0.23Ga0.77As/(Al)GaAs single quantum well separate confinement heterostructure lasers grown on (111)B GaAs have been studied under forward biased current injection. A room-temperature threshold current density of 750 A/cm2 is measured for a 1000 μm laser. The subthreshold electroluminescence spectrum blue shifts with increasing current up to the point of lasing threshold. Our measurements reveal that lasing is achieved while there is a strong residual or "unscreened'' electric field across the quantum well. Based on these observations we outline how piezoelectric quantum wells can be used to monolithically integrate a quantum well laser with a blue-shifting electroabsorption modulator. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: The photoluminescence linewidths of strained InxGa1−xAs/GaAs quantum wells grown on (111)B GaAs substrates are shown to differ radically from those grown on (001) substrates. In (111)B structures, the linewidth in wide wells is broadened significantly compared with (001) structures. This broadening cannot be explained by well width or alloy fluctuations alone, and suggests the presence of another mechanism which we believe is due to the piezoelectric field and its sensitivity to screening under illumination. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-2568Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary The serum concentration and urine excretion of LAP was determined by the method of Goldbarg and Rutenburg in 187 patients. Using their criteria, 9 of 17 patients with ampullary or pancreatic cancer, had elevations of LAP in their serum, urine, or both—characteristic of malignancy. Four additional patients had abnormal LAP levels of lesser magnitude. In the patients without pancreatic malignancy, elevations of LAP concentration, considered characteristic of cancer of the pancreas, occurred in the serum in 4 patients and in the urine in 22 patients. There was no correlation between the serum LAP levels by the Goldbarg and Rutenburg method as compared to the Fleisher method. The former appears to be more specific for pancreatic malignancy.Type of Medium: Electronic ResourceURL:
