Advanced Functional Materials, EarlyView.In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

The theory of direct magnetoelectric effect in the bilayer system of ferromagnetic–piezoelectric [PDF]
Journal of Advanced Dielectrics, 2016 The theory of direct magnetoelectric (ME) effect in a bilayer of ferromagnetic and piezoelectric is developed taking into account nonuniform distribution of electrical field on a piezoelectric layer thickness.

Study of orientation effect on nanoscale polarization in BaTiO3 thin films using piezoresponse force microscopy [PDF]
, 2005 We have investigated the effect of texture on in-plane (IPP) and out- of plane (OPP) polarizations of pulsed-laser-deposited BaTiO3 thin films grown on Pt and La0.5Sr0.5CoO3 (LSCO) buffered Pt electrodes.

Advanced Functional Materials, EarlyView.Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Modeling electromechanical properties of layered electrets: Application of the finite-element method
, 2004 We present calculations on the deformation of two- and three-layer electret systems. The electrical field is coupled with the stress-strain equations by means of the Maxwell stress tensor.
