据物理学家组织网4月14日报道,西班牙和美国科学家合作研制出一种基于石墨烯的光电探测器转化仪,其能在不到50飞秒(飞秒为千万亿分之一秒)的时间内将光转化为电信号,几乎接近光电转化速度的极限,将大力助推多个领域的发展。高效的光电转化技术,因为能让光所携带的信息转化成可在电子电路中进行处理的电信号,在从照相机到太阳能电池等多个关键技术领域发挥着重要作用,也是数据通讯应用的重要支撑。尽管石墨烯是一种拥有 According to the April 14 report of the Physicist’s Organization, scientists in Spain and the United States have jointly developed a graphene-based photodetector converter capable of operating at less than 50 femtoseconds ) Of the time the light into electrical signals, almost close to the limit of photoelectric conversion rate, will greatly promote the development in many areas. Efficient photoelectric conversion technology, because it can make the information carried by light into electrical signals that can be processed in electronic circuits plays an important role in many key technologies ranging from cameras to solar cells and is also important for data communications applications support. Although graphene is a kind of possession
