Van der Waals (vdW) dielectrics, materials with dielectric properties and affected by van der Waals forces, are commonly integrated within electronic devices, as they can help to preserve the properties of 2D semiconducting materials. So far, however, fabricating...
Researchers at Toyota Central R&D Labs have recently created an insect-scale aerial robot with flapping wings, powered using wireless radiofrequency technology. This robot, presented in a paper published in Nature Electronics, is based on a radiofrequency...
The efficient and large-scale conversion of carbon dioxide into fuels or other valuable substances could help to address the current energy crisis and mitigate the effects of global warming. One of the most effective approaches for converting CO2 into other...
Metal halide perovskites are a large class of crystalline materials with numerous advantageous features, including a high light absorption coefficient, high charge mobility and strong photoluminescence. Due to their unique properties, metal halide perovskites have...
Color centers are atomic imperfections in crystalline solids that absorb visible light of a particular color or radiation. These defects, typically in the form of missing atoms or substitutional impurities, can produce a characteristic color in materials that are...
To train and implement artificial neural networks, engineers require advanced devices capable of performing data-intensive computations. In recent years, research teams worldwide have been trying to create such devices, using different approaches and designs.
Nonlinear optics is a research field that explores how intense light interacts with matter. Typically, the optical response of materials is linearly associated with the amplitude of the electric field applied to them. At particularly high amplitudes, however, the...
Large-area electronics (LAE) is an emerging technology for electronic device manufacture, such as printing or large-scale lithography, the process used to create flat panel displays and solar cells. Using LAE processes, engineers could create systems that are large...
Semiconductor p-n junctions are boundaries between two types of semiconductors (i.e., p-type and n-type semiconductor materials). These junctions are crucial components of many modern electronic devices.
When fabricating electronic devices based on conventional semiconducting materials, engineers need to complete a crucial step known as doping. Doping essentially entails the introduction of impurities into semiconductors to enable the modulation of their optical,...
