Zero-gap semiconductor to excitonic insulator transition in Ta(2)NiSe(5)
The excitonic insulator is a long conjectured correlated electron phase of narrow-gap semiconductors and semimetals, driven by weakly screened electron–hole interactions. Having been proposed more than 50 years ago, conclusive experimental evidence for its existence remains elusive. Ta(2)NiSe(5) is...
