As few as five electrons in a semiconductor can exhibit collective behaviour, forming a “Coulomb liquid”, according to ...

Doping in organic semiconductors is achieved by removing a small fraction of electrons from the valence band. Holes, the absence of electrons, can then flow and conduct electricity.

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial ...

Definition: Band Gap Engineering is a process used in semiconductor material science to tailor the energy gap between the valence and conduction bands.This manipulation affects how electrons and holes ...

Although the researchers believe that the valence band can be empty in other materials, this effect is most visible in polymers. “We think that the way the energy bands are arranged in our polymer, as ...
