AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In the past decades, III-nitride semiconductor compounds have attracted an increasing amount of interest due to their applications to blue-violet laser diodes and white light emitting diodes, or for their use as ultraviolet emitting devices for biomedical ...
We report here photoluminescence studies of multilayer InAs quantum dot structures grown by MOVPE on (001)-oriented GaAs substrates. AFM measurements reveal prolate shapes of the dots, oriented along the [1-10] direction. Different orientations relative to ...
This thesis deals with the monolithic integration of long wavelength (1.3-1.55 µm) p-i-n photodiodes with HEMT field effect transistors for the realization of wide bandwidth OEIC receivers for lightwave communication systems. Part of this work was carried ...
Molecular beam epitaxy is used for the synthesis of catalyst-free GaAs nanowires and related quantum heterostructures. After growth of the nanowire GaAs core, the conditions are changed in situ towards standard MBE planar growth in order to obtain quantum ...
We report here photoluminescence studies of multilayer InAs quantum dot structures grown by MOVPE on (001)-oriented GaAs substrates. AFM measurements reveal prolate shapes of the dots, oriented along the [1-10] direction. Different orientations relative to ...
Hall electrical properties measured by the van der Pauw method and low-temperature photoluminescence (77 K PL) spectra of pseudomorphic GaAs/InyGa1-yAs/AlGaAs modulation-doped field-effect transistor-type heterostructures grown by molecular-beam epitaxy we ...
Molecular beam epitaxy Ga-assisted synthesis of GaAs nanowires is demonstrated. The nucleation and growth are seen to be related to the presence of a SiO2 layer previously deposited on the GaAs wafer. The interaction of the reactive gallium with the SiO2 p ...
Aluminum and gold nanowires were fabricated using 100 mm stencil wafers containing nanoslits fabricated with a focused ion beam. The stencils were aligned and the nanowires deposited on a substrate with predefined electrical pads. The morphology and resist ...
Thermally detected optical absorption (TDOA) and photoluminescence (PL) experiments are performed at 0.35 and 4 K, respectively, on InxGa1-xN(x less than or equal to 0.12) layers grown on GaN by molecular beam epitaxy. The modelling of absorption allows us ...
The lack of appropriate substrates has delayed the realisation of devices based on III-nitrides. Currently, the heteroepitaxial growth of GaN by metal organic vapour phase epitaxy (MOVPE) produces GaN layers which, despite huge densities of dislocations, a ...
