Carbon impurity has long hindered efficiency in nitride-based electronic and optical devices, but now researchers have discovered a method that can quickly detect carbon impurity using light.
Scientists have found a new way to detect the efficiency of crystal semiconductors, using a kind of photoluminescence spectroscopy to characterise the semiconductors.
Researchers claim to have synthetically generated homogeneous and defect-free crystals, which could be used to fast-track the commercialisation of perovskite solar cells.
The approach improves on current photoluminescence spectroscopy techniques and could lead to energy savings for mass producers, and thus consumers, of power devices.
New Zealand researchers have created a crystal-based device that could enable the next generation of faster, more energy-efficient internet.
A tiny electrical circuit — made from crystals of copper that are grown and electrically wired at nanoscale — may enable an entirely new design of digital devices.
Crystals made of boron arsenide have excellent thermal properties that can effectively dissipate the heat generated in electronic devices.
Higher-order topological insulators are crystalline solids with edges that conduct electric current while the rest of the crystal remains insulating.
Growing high-quality, crystalline 2D materials at scale has proven a significant challenge for researchers — until now.
Scientists at The University of Texas at Dallas have observed unusual behaviour in a sample of crystals, in a study published in the journal Chemical Communications.
Fujitsu has announced what is claimed to be the world's first technology for bonding single-crystal diamond to a silicon carbide substrate at room temperature.
Macquarie University researchers have made a single tiny diamond shine brightly — a behaviour known as superradiance — at room temperature, paving the way for nanodiamonds to be used in navigation, biomedical imaging, solar cells and more.
A Japanese researcher has identified new solid materials that could lead to the manufacture of non-toxic lithium-ion batteries.
Swiss researchers are extending the reach of quantum communications with a protocol based on a crystal that can emit quantum light, as well as store it for arbitrary long times.
Kyoto University researchers have demonstrated an on/off switching behaviour in a coordination polymer crystal.
