We report on the epitaxial growth of crystalline Si and Ge thin films by standard radio frequency plasma enhanced chemical vapor deposition at 175 °C (100)-oriented silicon substrates. also demonstrate epitaxially grown germanium layers so that multilayer samples sustaining epitaxy could be produced. used spectroscopic ellipsometry, Raman spectroscopy, transmission electron microscopy X-ray diffraction to characterize structure (amorphous, crystalline). These techniques were found provide...
Flowable electrodes, a versatile alternative to traditional solid electrodes for electrochemical applications, exhibit challenges of high viscosity and carbon content, limiting flow device performances. This study introduces colloidal suspensions thin multiwall nanotubes (MWCNTs) with diameters 10–15 nm as electrode materials. These nanotubes, stabilized in water surfactant, form percolated networks, exhibiting conductivity (50 ms/cm) stability at low content (below 2 wt%). Colloidal...
Potassium niobate–lead titanate solid‐solution nanoparticles have been synthesized using a new hydrothermal method. The key step is an in situ acid–base exothermic reaction with large excess of KOH , generating amorphous precipitated gel. This gel, when crystallized autoclave for 2 h at 190°C, produces mixed perovskite solid solution [ KNbO 3 ] 0.8 –[ PbTiO 0.2 ( KNPT ) composition, and parallelepiped particles rang size from few tens to hundreds nanometer length. study proves that the pure...
