Analysis of photoluminescence background of Raman spectra of carbon nanotips grown by plasma-enhanced chemical vapor deposition

Abstract: Carbon nanotips with different structures were synthesized by plasma-enhanced hot filament chemical vapor deposition and plasma-enhanced chemical vapor deposition using different deposition conditions, and they were investigated by scanning electron microscopy and Raman spectroscopy. The results indicate that the photoluminescence background of the Raman spectra is different for different carbon nanotips. Additionally, the Raman spectra of the carbon nanotips synthesized using nitrogen-containing gas precursor… Show more

“…Nanotips/Nanocones of different materials (carbon, silicon, poly silicon, GaN, GaP, sapphire, Al, AlN, ZnO, and ZnCdSeTe) have been produced using techniques such as self-masking dry etching technique in an electron cyclotron resonance (ECR) plasma process, vapor-liquid-solid (VLS) mechanism, thermal evaporation technique, chemical vapor deposition (CVD), plasmaenhanced hot filament CVD, Physical Vapor deposition [2][3][4][5][6][7]. However, the femtosecond laserinduced breakdown is attracting major interest of research for many investigators around the world for number of reasons.…”
