Scientists at ITMO University and their colleagues from the St. Petersburg Academic University and University of Tor Vergata (Italy) have developed high-performance perovskite solar cells. The improvement is thanks to the use of semiconductors based on wire-like nanocrystals.
Researchers from ITMO have demonstrated a novel technique for generation of laser radiation that utilizes perovskite metasurfaces. The solution will pave the way for next-gen lasers that are less than 100 nm thick and require significantly less energy.
The new device includes a structure of single-atom semiconductors and an ultracompact nanoresonator. The switching is conducted with light, via changes in the exciton states in each of the two semiconductor layers.
A research team featuring scientists from ITMO University and the City University of New York has successfully created controllable topological states that can be selectively excited on a silicon chip.
Students of ITMO’s School of Physics and Engineering have developed a prototype of a portable keyboard that is only 3 mm thick and provides haptic feedback. The new device is compatible with PCs, smartphones, and tablets, while its production cost amounted to less than 1,000 rubles.
