Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

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.

Over the past decade, a growing interest appeared for III-nitride semiconductors, in view of their potential applications in intersubband (ISB) devices. If these materials are nowadays famous, particularly for having revolutionized domestic lighting thanks ...

This article presents the dynamics of excitons in a-plane (Al,Ga)N/GaN single quantum wells of various thicknesses grown on bulk GaN substrates. For all quantum well samples, recombination is observed to be predominantly radiative in the low-temperature ra ...

We report the coupling and interaction between shallow donors and microcavities in bulk GaN at THz frequencies. At 4K, the shallow donors lead to an absorption at 23.5 meV (5.7 THz) under optical pumping above the bandgap of GaN. The microcavities are base ...

We report on the low-temperature growth of heavily Si-doped (>10(20) cm(-3)) n(+)-type GaN by N-rich ammonia molecular beam epitaxy (MBE) with very low bulk resistivity (
