Scientists determined that the electric field is responsible for alterating the fracture toughness of nanomaterials, which are used in state-of-the-art electronic devices. It is the first observed evidence that the electric field changes the fracture toughness at a nanometer scale.
Tandem solar cells based on silicon and perovskites have raised high hopes for future high efficiency solar modules. Researchers have now shown that an ultimate efficiency of 30% should be attainable with such tandem cells.
Use of copper as a fluorescent material allows for the manufacture of inexpensive and environmentally compatible organic light-emitting diodes (OLEDs). Thermally activated delayed fuorescence ensures high light yield.
Researchers used an ultrabright and ultrashort electron source to study the crystal structure of a platinum compound that comes from a family of materials with the ability to switch between insulating, metallic and superconducting states.
Organic-inorganic perovskite materials are key components of the new generation of solar cells. Understanding properties of these materials is important for improving lifetime and quality of solar cells.
Harnessing quantum systems for information processing will require controlling large numbers of basic building blocks called qubits. The qubits must be isolated, and in most cases cooled. Physicists have recently demonstrated important steps towards implementing a proposed type of gate, which does not rely on super-cooling their ion qubits.
