Graph Chatbot
Chattez avec Graph Search
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.
The conditions of splitting the reflectance, transmittance and absorption spectra of a dispersive symmetric Fabry-Perot microcavity are studied on the basis of classical multibeam interference formula, The special case of a monolithic semiconductor microca ...
We studied the formation of buried heterostructures obtained in a single growth step over nonplanar substrates patterned with ridges. When the ridge dimensions are large enough, the growth on the mesa top is similar to that on a planar substrate. In contra ...
We have studied the effect of growth interruptions on 2-monolayers-thick InAs/InP strained quantum wells (QW) grown by chemical beam epitaxy. The main feature is the formation of up to 8-monolayers-thick InAs islands during As2 annealing of the QW. Their f ...
We present a correlation between the behaviour of the RHEED specular reflected beam intensity during the initial phases of growth, the MBE growth conditions (T(s), P(As4), V(GaAs)), and the surface morphology examined by Nomarski contrast microscopy after ...
We have studied the electrical characteristics of p‐GaAs/n‐Si (100) heterojunction diodes grown by molecular beam epitaxy in an effort to determine the interface polarity. A Ga or As pre‐exposure was used prior to the growth of p‐GaAs on n‐Si substrates to ...
When InP is grown by chemical beam epitaxy on substrates patterned with ridges oriented along [110] with (111)B sidewall planes, the migration of In species on the surface changes direction with growth temperature. The movement is from the ridge to the val ...
We have studied the effect of growth interruptions on 2 monolayer thick InAs/InP strained quantum wells (QWS) grown by chemical beam epitaxy. The main feature is the formation of up to 8 monolayer thick InAs islands during As, annealing of the QW. Their fo ...
