چکیده
Photoluminescence spectra of tailored Ga~A1!P/GaP quantum well heterostructures exhibit strong short-wavelength peaks at 363, 560, and 6002700 nm. The peak at 560 nm seems to originate from a no-phonon transition. All the transitions are observed up to 200 K. Light emitting diodes made with the same heterostructure predominently emit 560 nm light ~green! with a background of 700 nm ~red! at room temperature under cw operation. © 1997 American Institute of Physics. @S0003-6951~97!02948-3#

Efficiency Studies of Semipolar GaInN-GaN Quantum Well Structures
In order to clarify the reasons for the fairly poor electroluminescence (EL) performance of semipolar LED structures grown on patterned sapphire wafers, we have analyzed both, pure photoluminescence (PL) test structures without doping only containing 5 GaInN quantum wells and full EL test structures, all emitting at a wavelength of about 510 nm. Evaluating the PL intensity over a wide range of ...

The present study was conducted to investigate current density of0.3 0.7 Al Ga N/ GaN multiple quantum well solar cell (MQWSC) under hydrostaticpressure. The effects of hydrostatic pressure were taken into account to measureparameters of 0.3 0.7 Al Ga N/ GaN MQWSC, such as interband transition energy, electronholewave functions, absorption coefficient, and dielectric con...
متن کاملInfluence of pressure on photoluminescence and electroluminescence in GaN/InGaN/AlGaN quantum wells
We have measured photoluminescence and electroluminescence in two different types of high-brightness single-quantum-well light emitting diodes manufactured by Nichia Chemical Industries with InxGa12xN active layers ~x50.45 and x50.15!, under hydrostatic pressures up to 8 GPa. We discovered that the pressure shift of the primary luminescence peak in each diode is very small: 12 and 16 meV/GPa fo...
متن کاملCharacteristics of InGaAsN-GaAsSb type-II ‘‘W’’ quantum wells
InGaAsN-GaAsSb type-II ‘‘W’’ quantum well structures have been grown by metalorganic chemical vapor deposition (MOCVD). Photoluminescence and X-ray diffraction measurements indicate that thin layers (2–2.5 nm) of GaAs1 ySby and InGaAs1 xNx can be grown with compositions of y 1⁄4 0:3 and x 1⁄4 0:02. ‘‘W’’ structures with different N contents indicate that emission wavelengths in the 1.4–1.6 mm r...
متن کاملPhotoluminescence and bowing parameters of InAsSb/ InAs multiple quantum wells grown by molecular beam epitaxy
Detailed studies are reported on the photoluminescence of InAsSb/ InAs multiple quantum wells grown by molecular beam epitaxy on InAs substrates with the Sb mole fraction ranging from 0.06 to 0.13. From 4 K photoluminescence the band alignment was determined to be staggered type II. By comparing the emission peak energies with a transition energy calculation it was found that both the conductio...
