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 demonstrate monocrystalline growth of GeSn on Ge and Si substrates by co-sputtering. We discuss the evolution of film growth with thickness, elucidating the effects of substrate temperature, sputtering source, and the importance of hydrogen dilution in ...
Perovskite solar cells have become strong contenders in the arena of photovoltaics due to the stunning rise in their efficiency from 3 % to over 20 % in just seven years. In this time, numerous device architectures and thin film deposition methods have bee ...
A novel molecular-ink deposition route based on thiourea and N,N-dimethylformamide (DMF) that results in a certified solar cell efficiency world record for non-vacuum deposited CuIn(S,Se)(2) (CIS) absorbers and non-vacuum deposited absorbers with a bandgap ...
Integrated wearable electronics capable of providing biophysical information on complex and dynamic systems have attracted high interest in diverse fields such as healthcare, gaming and robotics. Wearable sensors can create artificial, electronic skins wit ...
Perovskite solar cells have undergone increase in power-conversion efficiencies at an unprecedented pace. Since their emergence in academic research in 2009, thousands of scientific papers have been published on their unique properties, variations cell arc ...
The skin is not only the largest human organ, capable of accomplishing distributed and multimodal sensing functions. Replicating the versatility of skin artificially is a significant challenge, not only in terms of signal processing but also in mechanics. ...
This project focused on optimization of the deposition of platinum (Pt) thin films or use in piezoelectric MEMS/NEMS devices. Theory of piezoelectric, DC and DC-pulsed sputtering and thin film characterization was studied. Two parameters were varied in the ...
A novel glazing system consisting of a polymer layer with embedded micro compound parabolic concentrators (CPCs), which is attached to a glass pane of glazing, is proposed. It aims to reduce the energy consumption due to cooling in buildings, provide dayli ...
Cyanine dyes represent a class of ionic functional materials used by a broad heterogeneous science community contain-ing biologists, chemists, physicists and materials scientists. Their diverse application opportunities are ranging from fluorescence marker ...
