High purity platinum nanowire growth via field emission

This paper presents a single platinum nanowire growth with the length of 1.18 ¿m on the tip of a multi-walled carbon nanotube (MWCNT) via field emission. The MWCNT emitter was assembled with the nanorobotic manipulator for a cathode inside a field emission scanning electron microscope (FESEM). A tungsten probe was set for an anode as the opposite side controlled by the nanorobotic manipulator. We introduced the precursor cycopentadienyl trimethyl platinum IV (CpPtMe3) into the sample chamber of the FESEM. Field emission experiment at constant 1 ¿A for 1 minute was repeated 10 times to grow the platinum nanowire. The platinum nanowire was observed and analyzed from the spectra EDS data of transmission electron microscope (TEM). The purity of the platinum nanowire is 94.9 wt%.
