In the middle of the last century, it was demonstrated that with a decrease in the size of superconducting
structures, for example, the thickness of a thin film, its critical temperature Tc shifts by a certain amount.
It increases in aluminum, tin, and indium, and decreases in mercury, niobium and lead. However, there is
still no generally accepted ...

It is well known that new effects appear in superconductors with the reduction of their size. Among them one is the most interesting – phenomenon of changing of critical temperature. It can be both decrease and increase in different metals, however, despite the number of existing works, there is still no generally accepted conception of ...

In a metal sample, where at least one of the dimensions is comparable with the de Broglie wavelength of conduction electrons, the quantum size effects (QSE) should be observed. QSEs manifest themselves as non-monotonic dependencies of various material properties as function of relevant dimension. QSE should be particularly noticeable in materials with charge carrier(s) effective ...

Size-dependent quantization of energy spectrum of conducting electrons in solids
leads to oscillating dependence of electronic properties on corresponding
dimension(s) [1]. In conventional metals with typical energy Fermi EF~1 eV and
the charge carrier's effective masses m* of the order of free electron mass m0,
the quantum size phenomena provide noticeable impact only at nanometer
scales. Here we experimentally demonstrate ...

Quantum size phenomena develop when the dimension(s) of a system approach certain characteristic
scales. Modern nanotechnology enables routine and reproducible fabrication of
nanostructures with sub-100 nm features where such effects might be pronounced. In this research
we used lift-off lithography and vacuum metal deposition to fabricate bismuth (semimetal) and titanium (superconductor) nanowires. Then low energy argon ion beam ...
