摘要：

The angular dependencies of the linear bulk photovoltaic effect (BPE) under linearly polarized x-ray synchrotron radiation in LiNbO3: Fe, La3Ga5SiO14: Pr, and SiO2 have been revealed. This is the first observation of the tensorial properties of BPE under polarized x rays, which reveals giant values of the components of the photovoltaic tensor Gijk. The values of Gijk at 850 eV are 3-6 orders of magnitude higher than the corresponding values for the optical region. The present results may also explain the origin of x-ray photorefractive effect previously observed in LiNbO3: Fe. © 1995 The American Physical Society.
