Surface‐enhanced Raman scattering and fluorescence emission of gold nanoparticle–multiwalled carbon nanotube hybrids
Multiwalled carbon nanotubes (MWCNTs) are grafted with gold (Au) nanoparticles of different sizes (1–12 and 1–20 nm) to form Au–MWCNT hybrids. The Au nanoparticles pile up at defect sites on theExpand
Ni–Cr thin film resistor fabrication for GaAs monolithic microwave integrated circuits
Different Ni–Cr alloys were sputter-deposited on silicon nitride-coated GaAs substrates and covered with a spin-coated polyimide layer to develop thin film metal resistors for GaAs monolithicExpand
Growth and microstructures of carbon nanotube films prepared by microwave plasma enhanced chemical vapor deposition process
