Abstract

We have synthesized La-doped BaSnO₃ thin films on SrTiO₃ substrates by using the pulsed electron deposition technique. By performing reflection/transmission measurements on the films and a Drude model analysis of the data, we determined the carrier density n = 6.7 × 10¹⁹ cm^-3 and the room-temperature mobility μ = 17 cm²V^-1s^-1 of the conducting electrons. The standard Drude optical conductivity of the films demonstrates that the electron correlation effect is minimal in the present transparent conducting oxide material.
