The as-grown sample exhibits a roughly linear temperature dependence of the conductivity down to about 12 K, which is followed by a quite sudden drop to a very small conductance level. In this context we limit the presentation to an interrelated group of topics covering the importance of granular metals obtained from FEBID for basic research in correlation physics, as well as the potential for application of these granular metals in magnetic and strain sensing.
It is thus worthwhile discussing the Pt—Si system in some more detail. In the next subsection the continuum model will therefore be extended to a multicomponent variant. Since the local growth rates can be very high, reaching tens to hundreds of nanometers per second, growth proceeds far from equilibrium and is mainly kinetically controlled.
In the as-grown state the samples had a thickness of 80 nm. Lewis, Joo Hyon Noh, Jason D. Return to citation in text: • ACS Nano 2011, 5, 7781—7787. In general, the spectrum of secondary electrons depends on the properties of the substrate material and is characterized by a maximum in the low-energy region from 1 to 10 eV, followed by a tail to higher energies that roughly decreases with the third power of E.
- Summary and Main Conclusions. Experimental realization of the Ehrenberg-Siday thought experiment.
The magnetic analysis was performed by using off-axis magnetic holography in a transmission electron microscope TEM and provided evidence for the hard-magnetic nature of the FePt nanorods. The images were taken with an adapted MultiMode atomic force microscope with Nanoscope 3a controller at 0.
For details concerning the electronic transport properties of nanogranular FEBID structures the reader is referred to the next section. Modeling within the multicomponent continuum scenario: We now turn to a more in-depth analysis of the composition of the deposits obtained from the parallel dissociation of the two precursors.
It is directly apparent that the Pt—C system can be finely tuned through a insulator-to-metal transition. ACS Nano 2013, 7 1777-784. However, one has to keep in mind that the local growth rates in FEBID are high and that the beam-induced chemistry is presently neither well-understood nor well-controlled in most cases of single-precursor usage, not to mention precursor mixtures.
- Summary and Main Conclusions.
Furthermore, the extensibility of FEBID to the preparation of binary metals is discussed with a prospect of directly writing a wider range of magnetic or superconducting structures on the nanometer scale.
