Dear friend,
Scientists have discovered a new form of matter called the EXCITONIUM.
This matter is made up of a material called Boson. It's particles are four times more powerful than a proton carrying a positive charge, also has a negative charge and also a theoretical particle called the Tetraquark. It is a condensate that exhibits macroscopic quantum phenomena just like a superconductor. The electrons get excited and jump from the energy gap to the empty conduction band leaving behind a hole in the valence band.
Hope it helps !!!

Thanks for the answer ^__^
Welcome. :)
Which type of semiconductor does it exhibit
Or it can be doped???

Sir your answer is here:
As we know that our scientists thought about the new form of matter.
As we know that when an electron, seated at the edge of the crowded-with-electrons valence band in a semiconductor, gets excited and jumps over the energy gap to the otherwise empty conduction band, it leaves behind a “hole” in the valence band. That hole behaves as though it were a particle with positive charge, and it attracts the escaped electron. When the escaped electron with its negative charge, pairs up with the hole, the two remarkably form a composite particle, a boson - an exciton.
The team used a novel technique called momentum-resolved electron energy-loss spectroscopy (M-EELS) for the study. With their new technique, the group was able to measure collective excitations of the low-energy bosonic particles, the paired electrons and holes.
