IBM Demos Transistor with Liquid Nitrogen Cooling

Liquid nitrogen boils at just 77 Kelvins (-196 °C). Cooling electronics to this frigid temperature could boost performance, but today’s transistors aren’t designed with cryogenic temperatures in mind. At the 2023 IEEE International Electron Device Meeting (IEDM) held in San Francisco earlier in December, IBM researchers demonstrated the first advanced…

Butterfly-Eyed Sensors Capture UV Images

The compound eyes of an insect are structurally very different from that of a human—almost a separate category of organ altogether from the more familiar ocular arrangement of lens, cornea, iris, and retina. For instance, Papillio xuthus, the Asian Swallowtail Butterfly, can see wavelengths of light in the ultraviolet spectrum,…
