Israeli researchers and their colleagues recently published a paper in the United Kingdom journal Nature Communications, reporting an unusual superconducting phenomenon observed in NbSe2 ultrathin materials, which may contribute to the development of cutting-edge research fields like quantum computing. According to a bulletin released by the Hebrew University of Jerusalem, this material can exhibit superconductivity under certain conditions. The study analyzed the superconducting properties of NbSe2 films of different thicknesses. The results revealed that if the NbSe2 material becomes extremely thin, with only 3 to 6 layers of atomic thickness, or about 2 to 4 nanometers, its superconducting properties undergo previously unknown changes, with electric current becoming concentrated primarily at the upper and lower surfaces of the material, rather than throughout the entire material. The researchers noted that this was an unexpected change, indicating that superconducting mechanisms may have new characteristics at the nanoscale. This discovery could challenge some previous superconducting theories and is also expected to be used in research fields such as quantum computing and Sensor, helping to generate innovative application outcomes.
