a, SrTiO3 unit cell in the absence of a terahertz electric field. When a circularly polarized terahertz field pulse drives a circular atomic motion, dynamical multiferroicity is expected to create a net magnetic moment in the unit cell. b,c, The north pole points up for a pulse that is le...
So far, we have examined a simple case where the curvature of the electromagnetic wavefront around the beam axis can be regarded as a plane. Here we discuss a more general case where the curvature is not negligible. To achieve this condition, we positioned a sheet of 15-μm-thick Al foi...
Heterojunctions modulated internal electric field (IEF) usually result in suboptimal efficiencies in carrier separation and utilization because of the narrow IEF distribution and long migration paths of photocarriers. In this work, we report distinctive
Electrostatics: This is the sub-field of electromagnetics describing an electric field due to static (non-moving) charges. As an approximation of Maxwell’s equations, electrostatics can only be used to describe insulating, or dielectric, materials entirely characterized by electric permittivity. When...
