In physics, a "trion" refers to a quasiparticle that consists of three charge carriers, typically two electrons and a "hole," which is a missing electron in a semiconductor. Trions can behave like particles with fractional charges and are often studied in the context of two-dimensional materials, particularly in systems like transition metal dichalcogenides (TMDs).
