Wafer-scale MoS2 with water-vapor assisted showerhead MOCVD
Aleksandra Radenovic, Andras Kis, Mukesh Kumar Tripathi, Mukeshchand Thakur, Michal Daniel Macha, Yanfei Zhao, Hyungoo Ji
Among numerous thin film synthesis methods, metalorganic chemical vapor deposition performed in a showerhead reactor is the most promising one for broad use in scalable and commercially adaptable two-dimensional material synthesis processes. Adapting the m ...
ROYAL SOC CHEMISTRY2022Characterization of thin film stress for MEMS planarization
The synthesis and stress characterization of metal thin-films deposited on silicon wafers were performed on this project. Two different deposition techniques were employed: magnetron sputtering and Atomic Layer Deposition (ALD). Moreover, different tests w ...
2022Ultra low quantum decoherence nano-optomechanical systems
Thermal motion of a room-temperature mechanical resonator typically dominates the quantum backaction of its position measurement. This is a longstanding barrier for exploring cavity optomechanics at room temperature. In order to enter the quantum regime of ...
EPFL2022Development of stencil lithography for stretchable interconnects
The growing needs for human healthcare have driven the development of wearable devices for monitoring the health status of an individual. Polymers represent a promising platform for such devices due to their ability to form an intimate contact between soft ...
EPFL2022Nanobridge Stencil Enabling High Resolution Arbitrarily Shaped Metallic Thin Films on Various Substrates
Jürgen Brugger, Giovanni Boero, Yi-Chiang Sun
Stencil lithography (SL), which uses a perforated membrane as a reusable shadow mask to locally add material patterns on substrates provides a simple but versatile approach for the fabrication of functional devices on a large variety of substrate materials ...
WILEY2022From pulsed-DCMS and HiPIMS to microwave plasma-assisted sputtering: Their influence on the properties of diamond-like carbon films
Aïcha Hessler-Wyser, Johann Michler, Caroline Hain, David Brown, Thomas Nelis
The fabrication of high-hardness non-hydrogenated diamond-like carbon (DLC) via standard magnetron sputtering (MS) is often hindered by the low sputtering yields and ionisation rates of carbon, therefore investigations into pulsed alternatives of MS, else ...
ELSEVIER SCIENCE SA2022Colloidal transport and deposition through dense vegetation
David Andrew Barry, Li Chen, Congrong Yu
The effectiveness of submerged synthetic aquatic vegetation on removal of colloids from flowing water was investigated to explore retention of particulate nonpoint source pollutants in aquatic systems. In colloid transport experiments, the deposition rate ...
2022Enhanced radio-frequency performance of niobium films on copper substrates deposited by high power impulse magnetron sputtering
We present a study of radio frequency properties of niobium films deposited on copper by two different approaches based on High Power Impulse Magnetron Sputtering, namely with a DC voltage biased substrate and with bipolar target voltage. Such approaches e ...
2022Superconducting 2D NbS2 Grown Epitaxially by Chemical Vapor Deposition
Aleksandra Radenovic, Andras Kis, Mukesh Kumar Tripathi, Zhenyu Wang, Michal Daniel Macha, Yanfei Zhao, Guilherme Migliato Marega, Cheol Yeon Cheon, Hyungoo Ji
Metallic two-dimensional (2D) transition metal dichalcogenides (TMDCs) are attracting great attention because of their interesting low-temperature properties such as superconductivity, magnetism, and charge density waves (CDW). However, further studies and ...
2021Fast Hotspot Detection in SFCLs by Exploiting Strain Response in Optical Fiber Sensing
Luc Thévenaz, Nicolo' Riva, Zhisheng Yang, Arooj Akbar, Bertrand Dutoit
Superconducting fault current limiters (SFCLs) can be used to limit fault currents in both meshed DC and AC grids by transitioning from superconducting to resistive state, in the presence of high currents. While the device is theoretically a great way to p ...
