- excitation in the precursor as a consequence of its interaction with an impinging electron. Consequently, fundamental studies on chromium hexacarbonyl [22] and tungsten hexacarbonyl [23] included in this Thematic Series contribute to the important task of building a comprehensive database on the electron
Interactions of low-energy electrons with the FEBID precursor chromium hexacarbonyl (Cr(CO)6)

Beilstein J. Nanotechnol. 2017, 8, 2208–2218, doi:10.3762/bjnano.8.220
- density functional calculations (TDDFT) on the low-lying excited sates of tungsten hexacarbonyl, W(CO)6. The higher resolution obtained reveals previously unresolved spectral features of W(CO)6. The spectrum shows two higher-energy bands (in the energy ranges of 7.22–8.12 eV and 8.15–9.05 eV), one of them
- deposition (FEBID); photoabsorption; tungsten hexacarbonyl; Introduction The electronic structure of tungsten hexacarbonyl, W(CO)6, has previously been studied by using a variety of different experimental and theoretical methods, with experiments including vacuum ultraviolet experiments in the wavelength
- electron impact ionisation studies on the appearance energies of bare tungsten hexacarbonyl [28], on the fragmentation pathways of W(CO)6 clusters [29] and on the complete ligand loss of weakly bound W(CO)6 dimer [30]. As far as neutral dissociation (ND) is concerned, Zlatar et al. [25] have reported on

- . 4.3 Cobalt tricarbonyl nitrosyl; [Co(CO)3NO] and tungsten hexacarbonyl [W(CO)6] Cobalt tricarbonyl nitrosyl [Co(CO)3NO] was initially introduced in CVD as a liquid, easy-to-handle Co source. [76][77][78]. In CVD, Crawford et al. [78] reported an average composition of CoN0.5O0.9 with only traces of

We also discuss these results in the general context of the use of these precursors in FEBID and as part of the ongoing effort to understand the fragmentation mechanisms behind deposit formation. Finally, future perspectives and the relevance of these studies to establishing
Simulation of electron transport during electron-beam-induced deposition of nanostructures

- be discussed in section 5.5. A drawback of a solid-state doping source is the limited control over the dopant concentration during growth. To ensure a reproducible doping we studied the applicability of gaseous metal precursors, namely nickelocene Ni(C5H5)2 and tungsten hexacarbonyl W(CO)6, for the
- doping of diamond with nickel and tungsten. Both precursors are solids at room temperature but exhibit a high vapor pressure [20]. Nickelocene and tungsten hexacarbonyl, separately, were sublimated in a temperature-controlled dopant reservoir. Argon was passed through this reservoir, saturated with the
