Infrared study of giant dielectric constant in Li and Ti doped NiO

Jung-Ho Kim, Youngwoo Lee, A Souchkov +5

We have measured optical reflectivity of Li and Ti doped NiO (LTNO) in the infrared range at various temperatures. A Drude-like absorption is found at low energy, $ω <$ 100 cm$^{-1}…

Optical spectroscopy study on the electronic structure of $E u_{1 - x} C a_{x} B_{6}$

Jungho Kim, S. -J. Oh, Youngwoo Lee +4

The optical conductivity $σ_{1} (ω)$ of Eu $_{1 - x}$ Ca $_{x}$ B $_{6}$ has been obtained from reflectivity and ellipsometry measurements for series of compositions, $0 \leq x \leq 1$ . The…
