Seoul National University College of Engineering announced that a research team led by Prof. Yongtaek Hong from the Department of Electrical and Computer Engineering has developed a high-performance transparent organic light-emitting diode (OLED) incorporating highly conductive transparent metal mesh top electrodes fabricated using a selective metal deposition technique. The research was published in the journal Materials Horizons and was selected as the outside front cover image for the issue.

A joint research team has experimentally observed ballistic transport in single-crystalline copper thin films, demonstrating that ballistic transport is achievable in an industry-standard metal at interconnect-relevant dimensions. The study, titled "Ballistic transport in nanodevices based on single-crystalline Cu thin films," was published in Nature Communications.

If you shop on Google Flights, you get a quick comparison of different itineraries: One flight's carbon emissions may be average, while another's are 14% higher. But if you go shopping for a new laptop, you likely won't find quick, comprehensible information on different models' sustainability bona fides, despite the notable environmental impacts of producing and discarding electronics. In part, that's because understanding a device's emissions is difficult and time-consuming, even for experts.
