Materials nanoarchitectonics at two-dimensional liquid interfaces
Beilstein J. Nanotechnol. 2019, 10, 1559–1587, doi:10.3762/bjnano.10.153
- diffraction (GIXD) revealed a face-centred square grid structure with an average domain size of 3600 Å2. Makiura et al. employed a similar method to form multilayers of an oriented porphyrin-based MOF film on top of substrates by repeating transfer and washing of interfacially grown MOF layers (Figure 10
On the transformation of “zincone”-like into porous ZnO thin films from sub-saturated plasma enhanced atomic layer deposition
Beilstein J. Nanotechnol. 2019, 10, 746–759, doi:10.3762/bjnano.10.74
- represented in the scattering vector (qz) notation, where qz = 4π·sin(θ)/λ. Grazing incidence X-ray diffraction (GIXD) was performed to investigate the in-plane orientation of the crystallites, that is, with the crystallographic planes perpendicular to the substrate. The measurements were conducted at the
- incidence X-ray diffraction (GIXD). In Figure 4, the in situ XRD measurements performed during the calcination procedure for the zincone-like layers under investigation are presented. In a reference ZnO powder (26170-ICSD [67]), peaks are generally observed at qz positions of 2.23 Å−1, 2.41 Å−1, and 2.54 Å
- with the calcination temperature, suggesting a different preferential orientation of the ZnO grown under these conditions. In order to gather information also on the in-plane orientation of the ZnO crystallites, ex situ GIXD maps were acquired at synchrotron Elettra, Trieste, and are presented in
Growth, structure and stability of sputter-deposited MoS2 thin films
Beilstein J. Nanotechnol. 2017, 8, 1115–1126, doi:10.3762/bjnano.8.113
- position of the 00L peaks in specular X-ray diffraction (XRD) as well as broad diffraction features in grazing incidence X-ray diffraction (GIXD) experiments (Figure 3). However, the process of layer preparation is well controlled, which is reflected by the highly smooth surfaces. The RT deposited films
- thickness. The amorphous structure of the RT films is confirmed by the almost featureless GIXD image for the thicker 100 nm films (Figure 3b). For the 400 °C deposited 100 nm films the out-of-plane features in Figure 3c at qz of 0.9 Å−1 again indicate an increased interplanar d-spacing of 7.0 Å compared to
- and a PANalytical PIXcel3D detector were used. Grazing incidence X-ray diffraction (GIXD) Grazing incidence X-ray diffraction (GIXD) measurements were performed at the KMC-2 beamline at BESSY II (Berlin, Germany) using X-rays with a wavelength of 1.00 Å and a 2D cross-wire detector (BRUKER). An
Influence of calcium on ceramide-1-phosphate monolayers
Beilstein J. Nanotechnol. 2016, 7, 236–245, doi:10.3762/bjnano.7.22
- techniques as Brewster angle microscopy (BAM), infrared reflection–absorption spectroscopy (IRRAS) and grazing incidence X-ray diffraction (GIXD). The isotherms indicate that C1P monolayers are in a condensed state in the presence of calcium ions, regardless of the pH. At higher pH without calcium ions, the
- interesting calcium dependence was further investigated by means of grazing incidence X-ray diffraction (GIXD) at synchrotron facilities. The Langmuir trough is in an air-tight container filled with helium to avoid signal reduction due to absorption and scattering of photons in air. The incident beam is at an
- the details of GIXD measurements and analysis can be found in [16][17][18]. Figure 6 is shown as an example of the results obtained for C1P at pH 4 with calcium in the subphase. The contour plots display the diffracted intensities versus the in-plane (Qxy) and out-of-plane (Qz) components of the
Two step formation of metal aggregates by surface X-ray radiolysis under Langmuir monolayers: 2D followed by 3D growth
Beilstein J. Nanotechnol. 2015, 6, 2406–2411, doi:10.3762/bjnano.6.247
- , results in a second growth regime of silver nanocrystals. Here the formation of the oriented thin layer is followed by the appearance of a 3D powder of silver clusters. Keywords: GIXD; Langmuir monolayers; silver clusters; TXRF; X-ray radiolysis; Introduction Formation of metal nanoclusters and
- fluorescence signal (TRXF) simultaneously with the grazing incidence X-ray diffraction signal (GIXD) over a broad q-range covering the scattering wave vector transfer for the expected diffraction peak of 2D and 3D silver crystals. Figure 2, Figure 3 and Figure 4 present the diffraction spectra at different
- monolayer. GIXD was used to obtain in-plane information about the molecular structure of the surface. The spectra were obtained by varying the X-ray, momentum transfer, in-plane component qxy that is parallel to the air–water interface. The scattered intensity was measured as a function of the angle, 2θ
Magnetic properties of self-organized Co dimer nanolines on Si/Ag(110)
Beilstein J. Nanotechnol. 2015, 6, 777–784, doi:10.3762/bjnano.6.80
- self-organized Si NR array (pitch: 5 ∙ ≈ 2 nm) with a single domain orientation. This structure was confirmed by surface diffraction techniques (low energy electron diffraction, LEED and grazing incidence X-ray diffraction, GIXD) and large scale STM images [24][26]. The sharp spots of the 5 × 2
- superstructure displayed in LEED patterns and the narrow GIXD diffraction peaks associated with the 5× periodicity of the superlattice confirm the high structural order of the Si grating. It should be noted that to date, despite the numerous experimental and theoretical investigations on the Si/Ag(110) interface
