- Abstract
- We report on the interplane c-axis electronic response of FeTe0.55Se0.45 investigated by infrared spectroscopy. We find that the normal-state c-axis electronic response of FeTe0.55Se0.45 is incoherent and bears significant similarities to those of mildly underdoped cuprates. The c-axis optical conductivity sigma(c)(omega) of FeTe0.55Se0.45 does not display well-defined Drude response at all temperatures. As temperature decreases, sigma(c)(omega) is continuously suppressed. The incoherent c-axis response is found to be related to the strong dissipation in the ab-plane transport: a pattern that holds true for various correlated materials as well as FeTe0.55Se0.45.
