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.
We explored the degradation in electron beam pumped Zn1-xCdxSe/ZnSe laser structures by combining cathodoluminescence measurements in a scanning electron microscope with transmission electron microscopy. We found that degradation occurred via the formation ...
Synthesis of adenosine triphosphate (ATP) by the F1F0 ATP synthase involves a membrane-embedded rotary engine, the F-0 domain, which drives the extra-membranous catalytic F-1 domain. The F-0 domain consists of subunits a(1)b(2) and a cylindrical rotor asse ...
We explored degradation in electron-beam-pumped Zn1-xCdxSe/ZnSe laser structures by combining cathodoluminescence (CL) measurements in a scanning electron microscope with transmission electron microscopy. The rate of degradation, measured as the decrease o ...
The characterization of sub-micron gratings is usually performed on scanning electron microscopes, although the dimensions of the features often make the observations difficult. We report here on a new method applicable to III-V and II-VI semiconductors: w ...
A comparative image simulation and transmission electron microscopy (TEM) study has been addressed in order to assess whether NiAl intermetallic undergoes a crystalline-to-amorphous transformation directly induced by the cascade. For this purpose, an NiAl ...
Sol-gel derived lead zirconate titanate (PZT) thin films are being investigated for micromechanical applications. A synthesis technique which involves the spin coating of several thin layers followed by rapid thermal annealing to crystallize the perovskite ...
We present results obtained both with scanning electron microscopy (SEM) in the cathodoluminescence (CL) mode and transmission electron microscopy (TEM) on ZnCdSe/ZnSe electron-beam-pumped laser structures. This investigation aims at establishing a relatio ...
Discommensurations (DC) and domains in incommensurate charge density wave (CDW) states of the quasi-two-dimensional (PO2)4(WO3)2m (m = 12) bronze have been observed directly by dark-field transmission electron microscopy with use of the CDW satellite refl ...
The feasibility of using the LEEM technique in neurobiology was tested with experiments on a rat cerebellar granule cell culture. A series of good-quality images, showing fine details such as axons and dendrites of the neuron network, demonstrate that the ...
The high-pressure freezing (HPF) technique was applied to the cryo-immobilization of alginate gels and the quality of the freezing analyzed on a TEM by comparison of the segregation pattern of samples of decreasing thickness. Dynamic simulations of heat tr ...
