(GaIn)(AsP)- und (GaIn)(AsN)-Halbleiterheterostrukturen und ihre Anwendung in Diodenlasern
… von langwelligen (> 2 µm) InP-basierenden GaInAsP- und GaInAsN-Halbleiterheterostrukturen und ihre Anwendung in Diodenlasern wird beschrieben. <br>Zur Herstellung der Strukturen kamen die Metall-Organische Gasphasenepitaxie und die Molekularstrahlepitaxie zum Einsatz. Anhand von …

Leakage gate current in a heterostructure field effect transistor
… a function of the gate voltage for the AlI-nAs/GaInAs and AlGaAs/GaAs based HIGFET structures. For the AlInAs/GaInAs system, the calculated leakage currents are within a factor of 10 of the experimental values for most of the voltage range of study. This is more accurate than the results …

Temperature -Invariant Photoluminescence and Gain Spectra of Strained Gallium -Indium -Arsenide Quantum Wires
… 77 and 300 K has been derived for a SILO grown GaInAs QWR Fabry-Perot laser diode. The wavelength-shift rate of the gain spectra is ∼1.4 A/°C. These temperature stabilized gain spectra make the QWRs applicable to long-wavelength VCSELs. The temperature invariant gain spectra can be used …

Generalized detailed balance theory of solar cells
… of crystalline silicon, Cu(In,Ga)Se2 and GaInP/GaInAs/Ge triple cells were carried out and interpreted with the help of the reciprocity theorem. In case of crystalline silicon, the focus was on the investigation of recombination and light trapping with spectrally and spatially resolved EL. First …
