Dimensionality reduction and band quantization induced by potassium intercalation in 1$T$-HfTe${}_2$

Y. Nakata, K. Sugawara, A. Chainani +9

We have performed angle-resolved photoemission spectroscopy on transition-metal dichalcogenide 1$T$-HfTe${}_2$ to elucidate the evolution of electronic states upon potassium (K) depo…
