High-power diamond transistors Researchers from the University of Glasgow, RMIT University, and Princeton University created a new diamond transistor for high-power electronics that remains switched off by default. The performance of the diamond was improved by coating it in hydrogen atoms followed by layers of aluminum oxide. “The challenge for power electronics is that the design of the... » read more

Quiet qubits Researchers at the University of New South Wales Sydney recorded the lowest noise levels yet for a semiconductor qubit. Charge noise caused by material imperfections interferes with the information encoded on qubits, reducing accuracy. "The level of charge noise in semiconductor qubits has been a critical obstacle to achieving the accuracy levels we need for large-scale error-c... » read more

Plastic gold ETH Zurich has developed an 18-carat gold nugget based on plastic. Instead of traditional metallic alloy elements, ETH’s gold nugget consists of a matrix of plastic. Weighing five to ten times less than traditional gold, ETH’s plastic gold can be used in watches, jewelry, radiation shielding, catalysis and electronics. Gold is a chemical element used in a plethora of app... » read more
