Raw data for Role of the ferroelastic strain in the optical absorption of BiVO4

The following raw data are the basis of the paper "Role of the ferroelastic strain in the optical absorption of BiVO4" published in APL Materials in 2020 at http://doi.org/10.1063/5.0011507h. 

The UV/VIS measurements were carried out in air with a Jasco MSV-370 microspectrophotometer. The spectrophotometer operates a deuterium lamp for the UV and a halogen lamp for the visible and near infrared light range and collects the light using non-dispersive Schwarzschild objectives. Two samples have been investigated. The samples were cut and polished from a larger single crystal pulled by the Czochralski-method. The first sample has a (110) surface orientation and a thickness of 360 μm; the second sample has a (001)-oriented surface and a thickness of 100μm. The samples were placed in a Linkam THMS600 heating stage. Using an aperture, the measurement areas were set to 400μm x 400μm and 300μm x 300μm for the (110)-oriented sample and the (001)-oriented sample, respectively. For all reflectance measurements, an aluminium mirror was used for calibration.
