Abstract

In order to investigate band gap tunability in polar oxides, we measured the optical properties of a series of Bi(Fe_1−xMn_x)O₃ thin films. The absorption response of the mixed metal solid solutions is approximately a linear combination of the characteristics of the two end members, a result that demonstrates straightforward band gap tunability in this system.
