据物理学家组织网5月9日报道,美国加州大学河滨分校伯恩斯工程学院的研究人员开发出一种新技术,可借助石墨烯实现大功率半导体设备的大幅降温,解决在交通信号灯和电动汽车中使用的半导体材料散热问题。相关研究报告5月8日发表在《自然·通讯》杂志上。自上世纪90年代以来,半导体材料氮化镓(GaN)就被用于强光的制造,并因为高效和可耐高电压工作而被用于无线设备中。然而就像所有大功率操作设备一样,氮化镓晶体管会散发出相当多的热量,需要对其快速而有效的移除。科
According to a report by the Physicist Network May 9, researchers at the Burns School of Engineering, University of California at Riverside, have developed a new technology that can dramatically reduce the temperature of high-power semiconductor devices by using graphene. And the heat dissipation of semiconductor materials used in electric vehicles. Relevant research reports published in the May 8 in the “natural news” magazine. Since the 1990s, the semiconductor material, gallium nitride (GaN) has been used in the manufacture of glare and has been used in wireless devices for its high efficiency and resistance to high voltages. However, like all high-power operating devices, gallium nitride transistors emit considerable amounts of heat and require rapid and efficient removal. Section
