Evolution of charge dynamics in FeSe${}_{1-x}$Te${}_x$: Effects of electronic correlations and nematicity

M. Nakajima, K. Yanase, M. Kawai +6

We systematically studied in-plane optical conductivity of FeSe${}_{1-x}$Te${}_x$ thin films fabricated on CaF${}_2$ substrates for $x$ = 0, 0.1, 0.2, and 0.4. This system shows a la…
