Keywords: conducting atomic force microscopy (C-AFM); lead phthalocyanine (PbPc); molecular orientation; single-layer graphene; substrate effect; two-dimensional grazing incidence X-ray diffraction (2D-GIXRD); Introduction Organic semiconductors have been extensively used in
Subsurface imaging of flexible circuits via contact resonance atomic force microscopy
Beilstein J. Nanotechnol. 2019, 10, 1636–1647, doi:10.3762/bjnano.10.159
- thickness. Such a behaviour is due to the influence of the Si substrate. When the bottom layer becomes thicker, the substrate effect is less significant. For the middle layer thickness, there is an inflection point at approximately 300 nm. The contact stiffness contrast first drastically increases with
- increasing middle layer thickness and then decreases slightly after the inflection point is reached, which is also relevant with the substrate effect. Second, the influence of the mechanical properties of each layer was additionally investigated. Polymers including PMMA, HDPE, PS, PC and PI were used for the
Pull-off and friction forces of micropatterned elastomers on soft substrates: the effects of pattern length scale and stiffness
Beilstein J. Nanotechnol. 2019, 10, 79–94, doi:10.3762/bjnano.10.8
- expected to be present on a soft substrate when the adhesive micropattern is stiff compared to the substrate. Effect of geometry on pull-off forces on hard substrates Measurements on glass showed that sub-microscale samples tend to generate higher pull-off forces than flat samples and microscale samples
Surface-enhanced Raman scattering of self-assembled thiol monolayers and supported lipid membranes on thin anodic porous alumina
Beilstein J. Nanotechnol. 2017, 8, 74–81, doi:10.3762/bjnano.8.8
- SAMs, coupled according to the same thiol deposited on the different substrates of flat Au and tAPA–Au, are presented, for easier visualization of the substrate effect. It appears clearly that on tAPA–Au the major characteristic peaks of both MbA and AT are highly enhanced. Taking into account the

- (contact resistance, a dominant role of the recombination of carriers as compared to thermal generation, a substrate effect that provides the general mechanisms for room-temperature limitation of the carrier transport and even formation of a dual barrier diode). Results of DFT calculations Binding strength
Determination of the compositions of the DIGM zone in nanocrystalline Ag/Au and Ag/Pd thin films by secondary neutral mass spectrometry
Beilstein J. Nanotechnol. 2016, 7, 474–483, doi:10.3762/bjnano.7.41
- ). The substrate effect alone, in line with the results of [6] where the GB velocity was only slightly different for DIGM in the Au layers (in contact with Ag) on solid substrates or in free-standing films, also would not be enough to reverse the composition. On the other hand, the combined effect of the
The role of electron-stimulated desorption in focused electron beam induced deposition
Beilstein J. Nanotechnol. 2013, 4, 474–480, doi:10.3762/bjnano.4.56
- substrates Au(110) and a mixture of amorphous carbon and platinum [25]. This indicates that the factor of 2.5–3.0, which we observed here, cannot be explained solely by a substrate effect. This conclusion is consistent with the report from Christy for a siloxane [14] and from Li et al. for WF6 [16]. The
Growth behaviour and mechanical properties of PLL/HA multilayer films studied by AFM
Beilstein J. Nanotechnol. 2012, 3, 778–788, doi:10.3762/bjnano.3.87
- [21][37][38][40]. Another source of error in mechanical measurements of thin films is the substrate effect [37]. Although film stiffening due to the hard substrate is a real effect, it should be eliminated in the calculations since it does not reflect the material properties of the coating and may not
- larger than that from the thickness-corrected one. It was observed that the substrate effect is less stressed for thicker films, but it cannot be neglected for a film thinner than ≈5000 nm. Repetitive indentation measurements at one lateral position In order to test the reversibility of film deformation
Self-assembled monolayers and titanium dioxide: From surface patterning to potential applications
Beilstein J. Nanotechnol. 2011, 2, 845–861, doi:10.3762/bjnano.2.94
- substrate effect on the onset of burning and on the temperature dependence of the process [22]. Data on contact-angle comparisons between organosilanes on silica and on titania is quite scarce. In this respect, contact-angle measurements of CVD-made tetrafunctional cyclic siloxane monolayers (1,3,5,7
Direct monitoring of opto-mechanical switching of self-assembled monolayer films containing the azobenzene group
Beilstein J. Nanotechnol. 2011, 2, 834–844, doi:10.3762/bjnano.2.93
- appropriate for organic monolayer systems [16]. Another consideration for nanoindentation measurements is the substrate effect. "Buckle's rule" maintains that in order to gain information on the film only, and not the substrate, the depth of penetration into the film must not exceed 10% of the total film
