世界最薄LED厚度仅三个原子【通讯新闻】

元器件交易网讯 3月12日消息,据外媒报道,华盛顿大学已研发出仅有3个原子厚的世界最薄LED。

公司们正在为背光LED变薄以使设备更轻薄而不断努力,华盛顿大学似乎已经超越了所有人。科学家开发出仅有三个原子厚、目前为止最薄的LED—以目前的知识水平不可能有更薄的了。这种LED的关键成分是已知最薄的半导体硒化钨,单片材料不到常规LED厚度的十分之一。但仍可发出可测量到的光线,且材料可塑、强韧。在基础层面该技术可用于光学电路、纳米激光器及其他需要微照明的领域。研究人员同样希望这种LED可以用于移动设备—可以解决可穿戴及其他设备厚度由于厚度所带来的问题。(元器件交易网毛毛 译)

Companies have been racing to slim down LEDbacklights as devices get ever thinner, but the University of Washington mayhave just beaten everyone to the finish line. Its scientists have developed anLED that, at three atoms thick, is easily the thinnest LED to date in fact,it"s impossible to build something thinner using current knowledge. The keyingredient is tungsten diselenide, the thinnest known semiconductor. A singlesheet of the material is less than a tenth as thick as a conventional LED, but stillemits measurable light. It"s flexible and strong, too. On a basic level, thetechnology could be handy for optical circuits, nanolasers and other areaswhere miniscule lighting is necessary. However, the researchers also see usesfor their LED in mobile devices it could end up in wearables and othergadgets where even a slight difference in thickness could make a big impact.
