Engineering excitonic metal-insulator transitions in ultra-thin doped copper sulfides
Haiyang Chen, Yufeng Liu, Yashi Jiang +10
Delicate engineering of the bands remains challenging due to complex electronic, structural, and compositional interplay. We demonstrate the formation of distinct metallic and insu…
