Effects of focused electron beam irradiation parameters on direct nanostructure formation on Ag surfaces
Beilstein J. Nanotechnol. 2022, 13, 1004–1010, doi:10.3762/bjnano.13.87
- irradiation and the material of the surface. However, the effects on growth dynamics of numerous irradiation parameters, such as beam current or angle of incidence, have not yet been studied in detail. We explore the effects of focusing, angle of incidence, and current of the electron beam on the size and
- LiAlSi glasses [28] and TiO2 [29]. In one of our previous studies [30] we investigated the growth dynamics of nanodots on various metal surfaces (Al, Ag, Cu, Cr, and Mo) under focused EB irradiation in an SEM vacuum chamber. Similar to the previously discussed study, an influence of the surface material

- using these techniques, NWs are grown away from the substrate, usually in a tilted direction, and size distribution and geometry strongly depend on the growth dynamics [32][33]. Furthermore, it is known that the catalyst introduces uncontrolled and unwanted contamination inside the crystal lattice of
Growth dynamics and light scattering of gold nanoparticles in situ synthesized at high concentration in thin polymer films

We report on this phenomenon, considering the growth dynamics of gold nanoparticles in a polymer film. The scattering of light was

- , compared to uncoated glass coverslips using alamarBlue® proliferation assay [23]. The current contribution describes the growth of the films based on nucleobases in more detail. Results The growth dynamics of all three systems were investigated using in situ QCM, as shown in Figure 2 and Figure 3 and
- mode dominates the overall film growth. Such a CVD contribution is limited when a practical growth mode is considered sufficient. When highlighting the overall growth dynamics, rather long pulse and purge times for all precursors are used. In this case, a pulse scheme of 7 s TTIP, 10 s purge, 15 s
- and Ti-L-aspartic acid films where a contact angle of approximately 30° was measured on the surface of these materials in our previous study [22]. The growth dynamics of the individual systems were further investigated by adding an extra water pulse after the organic precursor to shed light on the
Dopant-stimulated growth of GaN nanotube-like nanostructures on Si(111) by molecular beam epitaxy
Beilstein J. Nanotechnol. 2018, 9, 146–154, doi:10.3762/bjnano.9.17
- diffusion flux [42]. In the absence of Si, a concentration of Ga adatoms on the sidewalls is not sufficient for GaN nucleation and no radial extension occurs. The growth dynamics changes when Si flux is applied: it has been demonstrated [27] that a high concentration of Si doping lowers the GaN nucleation
Electron beam induced deposition of silacyclohexane and dichlorosilacyclohexane: the role of dissociative ionization and dissociative electron attachment in the deposition process
Beilstein J. Nanotechnol. 2017, 8, 2376–2388, doi:10.3762/bjnano.8.237
- conducted the first EBID experiments with DCSCH and SCH, and we discuss these in the context of potential effects on the growth dynamics through the very different sensitivity of these molecules towards electrons of very low energy (<10 eV). Furthermore, both molecules are potential precursors for the

We have characterized and compared the growth dynamics of these compounds and the composition of the deposits formed, as well as the extent of the proximity effect under different deposition conditions and geometrical deposition arrangements. We have further discussed the

- material around it will be further removed by the bombarding ions within the Gaussian bell. The growth of the pore diameter with dwell time is eventually slowed down, thereby reflecting the tail of the beam profile. The pore growth dynamics is defined very precisely by the incident ion beam distribution

The crystallinity of the films is examined by X-ray diffraction (XRD). The topography of the films can be investigated

The particle growth dynamics can be explained in the frame of the LaMer model [12] which describes the growth process in two separate steps (Figure 1, blue line): above a critical concentration of free metal atoms, nucleation seeds are formed. Once the concentration
