Trions consist of three charged particles bound together by very weak bonding energy. Although trions can potentially carry more information than electrons in applications such as electronics and quantum computing, trions are typically unstable at room temperature, and the bonds between trion particles are so weak that they quickly fall apart. Most research on trions requires supercooled temperatures, and even then, their fleeting nature has made trions difficult to control and hard to study.
