ExcitoniumJanuary 12, 2020
Exciton, the combination of an electron and a positive hole (an empty electron state in a valence band), which is free to move through a nonmetallic crystal as a unit. Because the electron and the positive hole have equal but opposite electrical charges, the exciton as a whole has no net

10-12-2017 · Scientists have proven the existence of new form of matter called excitonium – which was first theorised almost 50 years ago. Researchers from University of California Berkeley and University of Illinois at Urbana-Champaign in the US studied non-doped crystals of the transition metal dichalcogenide titanium diselenide (1T-TiSe2).
Excitonium is a condensate, meaning what the researchers detected was a solid. Excitonium is made up of particles called excitons, in the same way that, say, solid aluminum is made up of aluminum.
10-12-2017 · Physicists discover a new form of matter called Excitonium, which was theorized 50 years ago. It’s made of excitons, particles formed in a strange quantum mechanical pairing. Momentum-resolved Electron Energy-Loss Spectroscopy (M-EELS) is used to discover it. Physicists at University of
Kogar admits, discovering excitonium was not the original motivation for the research—the team had set out to test their new M-EELS method on a crystal that was readily available—grown at Illinois by former graduate student Young Il Joe, now of NIST. But he emphasizes, not coincidentally, excitonium was a major interest:

ELSEVIER Journal of Alloys and Compounds 225 (1995) 133-138 Journal of ALLOY5 AND COMPOUND5 The discovery of excitonium Peter Wachter Laboratorium fiir FestkOrperphysik, ETH Ziirich, 8093 Ziirich, Switzerland Abstract The long-predicted existence of an excitonic condensed phase–i.e, the excitonic insulator–has been verified experimentally under pressure.
According to the researchers, excitonium is what’s known as a condensate. This means it exhibits macroscopic quantum phenomenon, like a superconductor, superfluid, or insulating electronic crystal.
