Controlling spin in antiferromagnetic insulators

Researchers from the Technical University of Munich (TUM), the Bavarian Academy of Sciences and Humanities, and the Norwegian University of Science and Technology (NTNU) in Trondheim have discovered a new method for controlling spin carried by quantized spin wave excitations in antiferromagnetic insulators. Elementary particles carry an intrinsic angular momentum known as their spin. For an ...

microLED ICs fabbed on 300mm wafers

Eight year-old Leti micro-LED spin-off Aledia has manufactured microLED ICs on 300mm (12”) silicon wafers. The company, which developed its technology on 200mm (8”) silicon wafers over the past eight years. “The larger size allows 60-100 smartphone displays to be made on a single 300mm wafer, versus approximately four-to-six using the present LED industry-standard, 4” ...
