Cyclic flow deposition
WebAug 31, 2024 · We have compared co-flow and cyclic deposition/etch processes for the selective epitaxial growth of Si:P layers. High growth rates, relatively low resistivities and significant amounts of tensile strain (up to 10 nm min −1, 0.55 mOhm cm and a strain equivalent to 1.06% of substitutional C in Si:C layers) were obtained at 700 °C, 760 Torr … WebThe Electrodeposition Module is suited for a wide variety of applications, including: metal deposition for electronics and electrical parts; corrosion and wear protection; decorative electroplating; electroforming of parts …

WebNov 1, 2016 · Thus, there are inherent differences for particle depositions under cyclic and steady flow conditions. Zhang et al. (2002) indicated that the deposition of micro-particles in a bronchial airway model is higher under cyclic flows compared with that predicted by the equivalent mean flow assumption. WebDec 1, 2024 · In this work, NbOx-based selector devices were fabricated by sputtering deposition systems. Metal-to-insulator transition characteristics of the device samples were investigated depending on the oxygen flow rate (3.5, 4.5, and 5.5 sccm) and the deposition time. The device stack was scanned by transmission electron microscopy (TEM) and …
