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.

Does a Morphotropic Phase Boundary Exist in ZrxHf1‐xO2‐Based Thin Films?
Advanced Functional Materials, EarlyView.This study investigates 6 nm zirconium‐rich hafnium‐zirconium oxide thin–film metal–insulator–metal capacitors using a combination of experimental methods and machine learning–based molecular dynamics simulations to provide insight into the physical mechanisms that enhance the dielectric constant near 0 V and attribute it to the field‐induced ...

Temperature dependence bending rigidity of 2D membranes: Graphene as an example
AIP Advances, 2018 Bending rigidity plays an important role in graphene from mechanical behavior to magnetic and electrical properties. However, it is still in a theoretical debate whether the bending rigidity of graphene increase or decrease with increasing temperature ...

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 ...
