Charge transfer in the high dielectric constant materials CaCu3Ti4O12 and CdCu3Ti4O12
C. C. Homes, T. Vogt, S. M. Shapiro +3
The cubic perovskite-related ceramic CaCu3Ti4O12 has a very high static dielectric constant ~10000 at room temperature (RT), which drops to about 100 below about 100 K. Substitutin…

Charge dynamics and metal-insulator transition in SiGd and SiY alloys
D. N. Basov, A. M. Bratkovsky, P. F. Henning +5
Carrier dynamics in amorphous a-SiRE (RE=Gd, Y) films has been studied in the doping regime close to the metal-insulator transition by means of infrared spectroscopy.…
