The next wonder semiconductor

In a study that confirms its promise as the next-generation semiconductor material, researchers have directly visualized the photocarrier transport properties of cubic boron arsenide single crystals.

Greenbelts are effective at slowing urban sprawl

Researchers argue that greenbelts almost always work in curbing sprawl, particularly in larger cities. It looks at 60 cities in Europe, half of them with a greenbelt, half without, and uses open-source data to compare changes in and levels of urban spr…

Miniaturized infrared detectors

Extreme miniaturization of infrared (IR) detectors is critical for their integration into next-generation consumer electronics, wearables and ultra-small satellites. Thus far, however, IR detectors have relied on bulky (and expensive) materials and tec…
