Published 1997Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We report on photoluminescence (PL) and photoluminescence-excitation measurements in GaAs/In0.1Ga0.9As/AlAs double-barrier tunneling structures as a function of bias voltage and temperature. We have observed a splitting in the quantum well photoluminescence due to island formation in the quantum well. We have a good correlation between the variation of integrated PL intensity, linewidth, and tunnel current bias for both lines. The temperature dependence of photoluminescence spectra shows that transfer of carrier between islands can be tuned by the applied bias and that states in different islands are populated by electrons in the resonant tunneling process. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We analyze the current density-voltage characteristics of double-barrier tunneling diodes, with different spacer layers, within the framework of a Poisson solver together with a coherent tunneling approximation for transmission probabilities. We show that varying the spacer layer thickness, together with barrier heights, changes dramatically the current density-voltage characteristics line shape, which is revealed to be an important qualitative signature of the tunneling paths involved in the double-barrier diodes under operation. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0509Keywords: Key words: Invagination—Intussusception—Jejunogastric—Gastric surgery.Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract. Jejunogastric intussusception is a rare complication of gastric surgery. We report a case in a 41-year-old woman subjected to gastrojejunostomy with truncal vagotomy 3 years before for pyloric stenosis. The jejunogastric intussusception was diagnosed by upper gastrointestinal series, ultrasonography, and computed tomography. Surgical management consisted of reduction and fixation. Treatment should be as early as possible to prevent gangrene of the invaginated segment.Type of Medium: Electronic ResourceURL:
