Tunnelling Contact Helps to Study Electron Structure of Carbon Nanotubes

Tunnelling Contact Helps to Study Electron Structure of Carbon Nanotubes
Russian physicists have demonstrated how tunnelling contacts can be used for single-particle states spectroscopy in carbon nanotubes. The proposed technology of tunnelling contact fabrication and the spectroscopic method will help measure the exact nanotube bandgap value, which is the key characteristic required for design of any nanotubes-based electronic devices. Applied Physics Letters publishes the result of the study.

HSE MIEM: Physics of New Materials, Quantum Methods and Technologies
Andrey Vasenko, Professor at the School of Electronic Engineering and Deputy Head of the Quantum Nanoelectronics Laboratory, speaks about studying superconductors and superconductivity and researching materials for solar energy harvesting, including perovskite structures.

Researchers Compare Energy Consumption During Extraction and Synthesis of One Diamond Carat

Researchers Compare Energy Consumption During Extraction and Synthesis of One Diamond Carat
Researchers from HSE University, RAS, and Skoltech have compared actual specific energy consumption in the production of diamonds using traditional (mining) and innovative (synthesis) methods. Depending on the technology, 36 to 215 kWh of energy is consumed to produce a 1 carat diamond. It turned out that not all diamond synthesis technologies surpass extraction methods in terms of energy efficiency. The results of the study were published in the journal Energies.

Researchers Begin to Understand Correlation of Schumann Resonances and Dust Storms on Mars

Researchers Begin to Understand Correlation of Schumann Resonances and Dust Storms on Mars
The interaction of dust particles in Martian dust storms may cause electric fields that are powerful enough to have charges that induce standing electromagnetic waves known as Sсhumann resonances. This is the conclusion drawn by physicists from HSE University, the Space Research Institute, and MIPT. The paper was published in Icarus journal.

Statistical Physics Can Help Uncover the Impact of Media on Decision Making

Statistical Physics Can Help Uncover the Impact of Media on Decision Making
Students and researchers from HSE University and the Landau Institute for Theoretical Physics have examined the widely known ‘Prisoner’s Dilemma’ game using methods from statistical physics. They used the mean-field concept, a common tool for studying the physics of many-particle systems, to describe human decision-making processes. Researchers suggest that this model may be helpful for understanding systems with many participants. The results of the study are published in the September issue of the Physics Review Research journal.

Scholars Gain New Data on Heavy Exotic Hadrons

The Belle detector
As part of the Belle experiment, researchers were able to measure the energy dependence of e+e- -> B-anti-B, B-anti-B* and B*-anti-B* reactions in the 10.63 GeV to 11.02 GeV energy range for the first time. The new data will help clarify the nature of the group of exotic Upsilon mesons that have mass in this range. The results of the study were published in the Journal of High Energy Physics.
