A physical effect known as superinjection underlies modern light-emitting diodes (LEDs) and lasers. For decades this effect was believed to occur only in semiconductor heterostructures — that is, structures composed of two or more semiconductor materials. Researchers from the Moscow Institute of Physics and Technology have found superinjection to be possible in homostructures, which are […]
Physicists Upgrade Cheap Diode Laser for Use in Precise Measurements
Russian physicists have developed a method for drastically narrowing the emission spectrum of an ordinary diode laser, like that in a laser pointer. This makes their device a useful replacement for the more complex and expensive single-frequency lasers, enabling the creation of compact chemical analyzers that can fit into smartphones, cheap lidars for self-driving cars, […]
Linear Equations System Will Restore Impaired Hand Motion
Researchers from the Moscow Institute of Physics and Technology have developed a model for predicting hand movement trajectories based on cortical activity: Signals are measured directly from a human brain. The predictions rely on linear models. This offloads the processor, since it requires less memory and fewer computations in comparison with neural networks. As a […]
Prototype Nuclear Battery Packs 10 Times More Power
Russian researchers from the Moscow Institute of Physics and Technology (MIPT), the Technological Institute for Superhard and Novel Carbon Materials (TISNCM), and the National University of Science and Technology MISIS have optimized the design of a nuclear battery generating power from the beta decay of nickel-63, a radioactive isotope. Their new battery prototype packs about […]
Researchers Offer New Technology For Liquid-Crystal Displays
An international research team from Russia, France, and Germany has proposed a new method for orienting liquid crystals. It could be used to increase the viewing angle of liquid-crystal displays. The paper was published in the journal ACS Macro Letters. “This is first and foremost a fundamental study exploring the mechanisms of liquid crystal orientation,” says […]
Electromagnetic Wizardry: Wireless Power Transfer Enhanced By Backward Signal
An international research team including scientists from the Moscow Institute of Physics and Technology and ITMO University has proposed a way to increase the efficiency of wireless power transfer over long distances and tested it with numerical simulations and experiments. To achieve this, they beamed power between two antennas, one of which was excited with […]
MIPT Delivers World’s First Biosensor Chips Based On Copper And Graphene Oxide
Russian researchers from the Moscow Institute of Physics and Technology have developed biosensor chips of unprecedented sensitivity, which are based on copper instead of the conventionally used gold. Besides making the device somewhat cheaper, this innovation will facilitate the manufacturing process. The research findings are reported in the journal Langmuir, named in honor of Irving Langmuir […]

Physicists Reveal Material For High-Speed Quantum Internet
The race for quantum computing is on: Industry giants, such as Google, IBM, and Microsoft, and leading international research centers and universities are involved in the global effort to build a quantum computer. It is not known yet when this new technology can become a reality, but the world is getting ready. The greatest expectation […]
MIPT Physicists Tune A Spin Diode
A team of physicists at MIPT has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes, it is possible to change the resistance and the resonant frequency of the diode. In addition, this approach triples the range of frequencies […]
