For the first time an international research group has revealed the core mechanism that limits the indium content in indium gallium nitride thin films - the key material for blue light emitting diodes (LEDs).
Researchers used a new method for synthesizing iron-dysprosium garnet. Magnetic materials of this class are used in microwave and magnetic photon equipment. Iron-dysprosium garnet is understudied and may have previously unknown properties.
Researchers discovered that a form of perovskite works surprisingly well as a stable and photoactive semiconductor material that can be reversibly switched between a transparent state and a non-transparent state, without degrading its electronic properties.
Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip.
