Weil fermions, special types of particles, are known for their unusual electromagnetic properties and have long been the focus of researchers. However, most of the materials studied so far contained undesirable electronic states that dwarfed the veil fermin.
The new material, developed by an international group under the leadership of Japanese Riken, is the first to feature a pair of Weil Fermons without unrelated electronic conditions. The study, published in the journal Nature, was based on a topological semiconductor called Tedluuride Wismuth, which was modified by replacing some of its gamut atoms with chromium.
Weil’s new half could find wide use in terariate devices used to detect and produce light at extremely high frequencies. The team also includes its use in high-performance sensors, low-power electronics and novel optoelectronic devices.
