A fluorine free copper precursor, Cu(tbaoac)2 with the chemical sum formula CuC16O6H26 is introduced for focused electron beam induced deposition (FEBID). FEBID with 15 keV and 7 nA results in deposits with an atomic composition of Cu:O:C of approximately 1:1:2. Transmission electron microscopy proved that pure copper nanocrystals with sizes of up to around 15 nm were dispersed inside the carbonaceous matrix. Raman investigations revealed a high degree of amorphization of the carbonaceous matrix and showed hints for partial copper oxidation taking place selectively on the surfaces of the deposits. Optical transmission/reflection measurements of deposited pads showed a dielectric behavior of the material in the optical spectral range. The general behavior of the permittivity could be described by applying the Maxwell–Garnett mixing model to amorphous carbon and copper. The dielectric function measured from deposited pads was used to simulate the optical response of tip arrays fabricated out of the same precursor and showed good agreement with measurements. This paves the way for future plasmonic applications with copper-FEBID.

Effect of 2 MeV electron beam at the current density 0.09 nA/cm2 on surface structure, nanocrystallite size of (ZrTi)CN nanocomposite coating on steel was investigated at Scanning Electron and Atomic Force microscopes, and also X-ray diffractometer. Using the Rietveld method, two structure phases were indentified in the pristine samples: (ZrTi)(CN)-cubic (space group Fm-3m) and TiC — trigonal (sp.gr.R-3m). Electron beam irradiation to the fluency of [Formula: see text] electron/cm2 resulted in the phase transition of TiC from trigonal (sp.gr.R-3m) to cubic structure (sp.gr.Fm-3m). Besides, nanocrystallite size and shape have changed after the fluency [Formula: see text] electron/cm2. The lattice parameters have increased up to [Formula: see text] electron/cm2 fluence and the nanorcrystallite size of nanocomposite was enlarged 26%, which was attributed to generation of defects.

General Perspective

The aim of the present overview article is to raise awareness of an essential aspect that is usually not accounted for in the modelling of electron transport for focused-electron-beam-induced deposition (FEBID) of nanostructures: Surface excitations are on the one hand responsible for a sizeable fraction of the intensity in reflection-electron-energy-loss spectra for primary electron energies of up to a few kiloelectronvolts and, on the other hand, they play a key role in the emission of secondary electrons from solids, regardless of the primary energy. In this overview work we present a general perspective of recent works on the subject of surface excitations and on low-energy electron transport, highlighting the most relevant aspects for the modelling of electron transport in FEBID simulations.
