The dynamics of thermal radiation accompanying the condensation of tungsten nanoparticles in superfluid helium and vacuum was studied experimentally in the visible range. It was shown that during the first 100 μs the accompanying thermal energy of p

The technique of simultaneous coagulation of two different materials in superfluid helium has been implemented, which allows one to create different ultrathin (d < 8 nm) heterostructures. A simultaneous ablation of two metal targets (indium and plati

Metal atoms and small clusters introduced into superfluid helium (He II) concentrate there in quantized vortices to form (by further coagulation) the thin nanowires. The nanowires’ thickness and structure are well predicted by a double-staged mecha

As in the case of metals, laser ablation of germanium and silicon in superfluid helium leads to the formation of thin nanowires; spherical nanoclusters are also present in ablation products. A decrease in the resistance of bundles of silicon nanowire

A mobile measuring cell was proposed and created using a focused ion beam as a nanoknife for measuring the electrical characteristics of individual nanowires and nanotubes by the four-wire method. The cell consists of two elements: the basic one, on

The possibility of using miniaturized low-power electric motors submerged in superfluid helium for organization of rotation inside a cryostat has been investigated. It has been revealed that many of commercial micromotors can operate in liquid helium

It has been shown that micrometer-sized balls, resulting from the condensation of products of laser ablation of fusible metals in both superfluid helium and water, are in the state of strong internal tension counterbalanced by external compression. B

The process of condensation of metal atoms in superfluid helium was shown to occur mainly in the quantized vortices. Firstly the spherical nanocrystals were grown there. At low metal content in liquid they fused then into long cylindrical nanowires.

It is shown that metallic nanowires (5–8 nm in diameter) that form during laser ablation of Ni, Pb, In, and Sn targets embedded in HeII contain extended single-crystal segments, while spherical clusters (about 2 μm in diameter) that form under the

Laser ablation of metals in superfluid helium has been used to obtain nickel, indium, and lead nanowire bundles. Wires 5–8nm in diameter demonstrate metallic conductivity and are coupled with one another by point contacts. It is shown that the wire
