Objective
Within the applied proposal, the investigations of single-crystalline low-dimensional metallic structures (LDMS), namely, thin films and nanostructures, possessed large electron mean free path (MFP), will be performed with regards to their electron transport properties, their morphology and also crystallographic and electronic structure. Our aim is to investigate the transport properties of a new type of LDMSs in which electrons propagate without being scattered except at the surface. This transport regime is called the "rough wave-guide" regime, because electron propagation in these structures is similar to electromagnetic wave propagation in wave-guides with rough surfaces. These single-crystalline LDMS are carved in thin films epitaxially grown using the methods we have recently developed (TC). Our preliminary results have shown that the electronic bulk mean-free-path is indeed long enough to reach the rough wave-guide regime, and we have already demonstrated that this new regime is markedly different from the usual diffusive transport regime.
We intend to investigate thoroughly an electron transport in LDMSs, employing also the results of investigations of their structure during fulfilment of the proposal. We suppose to perform the experiments for investigations of both bulk and interface crystallographic structure down to atomic scale resolution, as well as morphology to define true correlation roughness functions (T1), and also an electronic structure with direct evidence of formation of quantum well states (QWS) due to spatial quantisation of transverse electron motion using UPS (ultra-violate photoelectron spectroscopy) experiments down to 10 K (T2).
Magneto-transport experiments with high magnetic field to be in- and out-off-plane of LDMSs (T3), as well as bend and Hall resistance experiments, supported by Monte-Carlo simulations, (T5.1) are for basic transport investigations, aimed to determine how far semi-classic approaches do account for the observations.
Transverse magnetic focusing experiments should give estimation of specular reflection (T5.2) and effective MFP as a function of an electron path It is for direct evidence the transverse electron wave states with small amount of the nodes possess long damping length (T3.2).
Investigation of size effect in electron transport of LDMSs (T4.1) that going in with density-of-states (DOS) experiments (T2.2) should support the conclusion about transverse spatial quantisation effect and its dependence on electron-phonon scattering yield. Numerical simulations using experimental correlation roughness function, bulk MFP and DOS results are for verification of wave guiding approach for transverse electron motion (T4.2 T5.2).
Coherent transport experiments (5.3) should answer is any electron wave guiding effect in longitudinal (along current flow) electron transport. Specific properties due to non-local superconductivity for simple superconducting LDMSs are expected, and its application for X-ray detector is designed (5.3).
Research program includes different experimental approaches and methods of different participants from France, the Netherlands, Sweden, and two from Russia, that/who joined by aim to get fundamental understanding of wave guiding transport in single-crystalline LDMSs with large MFP, considering them as rough electron wave-guides.
