Low-dimensional perovskite-related metal halides have emerged as a new class of light-emitting materials with tunable broadband emission from self-trapped excitons (STEs). Although various types of low-dimensional structures ...
Engineered heterostructures or layered materials made with complex oxide materials are a rich source of emergent technical phenomena and applications. Materials scientists aim to develop new materials functionalities by interfacing ...
Two-dimensional (2-D) organic-inorganic halide perovskites are emerging materials for photovoltaic and optoelectronic applications due to their unique physical properties and a high degree of tunability. Despite impressive ...
Solar energy researchers at Oregon State University are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago.
Light-emitting diodes (LEDs) release energy in the form of light when electrons and "holes" (electron vacancies) recombine in response to an applied voltage. Over the past few years, scientists have turned their attention ...
Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel.
Grain boundaries, which consist of periodic arrangement of structural units and are generally recognized as a two-dimensional "phase," can exhibit novel properties that do not exist in the intrinsic bulk crystal. The altered ...
Strain-sensitive barium strontium titanate (Bax-Sr1-x-TiO3) perovskite systems are widely used for their superior nonlinear dielectric behaviors. In a new report on Science Advances, D.L. Ko and a research team in materials ...
The all-optical switch is a kind of device that controls light with light, which is the fundamental building block of modern optical communications and information processing. Creating an efficient, ultrafast, and compact ...
Organic-inorganic halide perovskite quantum dots (PQDs) form an attractive class of materials for optoelectronic applications. Their charge transport properties are, however, inferior compared to materials such as graphene. ...
