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 photoluminescence (PL) and PL-excitation (PLE) spectra of InyCa1-yAs/AlxGa1-xAs compressively strained V-groove quantum wires (QWR's) are compared to that of lattice-matched GaAs/AlyGa1-xAs QWR's with the same wire geometry. The PL is preferentially po ...
The dye solar cell, is a novel photoelectrochemical solar cell presenting unique advantages, as the use of low cost materials and the potential simplicity of manufacturing. However, a liquid electrolyte is actually required for the transport of the photoge ...
Presents a synchrotron radiation photoemission study of the upper-valence-band states of four ZrSe3-structure compounds: ZrS3, ZrSe3, ZrTe3 and HfSe3. The sulphide and selenide spectra exhibit a charac ...
Selective photoluminescence experiments have been used to analyse the neutral donor bound exciton spectra in n type wurtzite GaN epitaxial layers deposited on 6H-SiC, Al2O3 and GaN substrates, In heterostructure layers, the existence of residual strain dis ...
The electron injection rate of bis(Bu4N) cis di(thiocyanato) bis (2,2'-bypiridine-4,4' carboxylic acid)Ruthenium (II) dye (N719) into SnO2 nanocryst. thin films was measured with 2-color femtosecond transient absorption spectroscopy. The electron injection ...
A brief review is given of optical experiments related to the creation and recombination of charged excitons. The fundamental parameters of these states are discussed. This includes their energies, optical transition probabilities, and characteristic times ...
Contactless dye-sensitised nano-photoelectrodes assembled at polarisable liquid|liquid interfaces exhibit photocurrent responses originating from the heterogeneous photooxidation of ferrocene by the colloids. The photocurrent spectra of the nanoparticle as ...
