Researchers found a new method of photonic cooling by running LED with electrodes reversed. Researchers believe that this approach could improve cooling technology for future microprocessors, which will include various transistors in a small space that current methods cannot remove heat quickly enough. The finding was published on Nature on February 13 by a research team at the University of Michigan. Linxiao Zhu, the lead author on the research article, explained, “Usually for thermal radiation, the intensity only depends on temperature, but we actually have an additio...
