Sodium cyclopentadienyls were reported to be applied as precursors for the MOCVD growth of Na-containing thin films.
Sodium cyclopentadienyl (sodium cyclopentadienide) NaCp (M= 88.085 g/mol) is colourless solid, although samples often are pink owing to traces of oxidized impurities. NaCp is soluble in THF.
Sodium cyclopentadienyl NaCp was reported to be applied as Na source for the growth of Na-doped ZnO thin films by low pressure MOCVD, the presence
of Na in the layers was confirmed by SIMS. Local density of states (LDOS) of the Na-doped ZnO thin films at nanometer scale was determined by low-temperature scanning tunneling
microscopy (STM) and scanning tunneling spectroscopy (STS). The spatial distribution of the LDOS as well as the conductivity type was correlating to spatial variations of Na doping level, as was indicated by the local measurements.[i]
