摘要
锑化铟具有半导体中最高的电子迁移率和饱和速度,因此具有超低功耗的超高频工作潜力。非优化、非冷却量子阱异质结场效应管,栅极长度为85nm,在0.5 V Vds下截止频率为340GHz。该技术在未来超过100GHz的微波应用中显示出非常有前景
Indium Antimonide based Quantum Well FETs for Ultra-high Frequency, Low Power Dissipation Circuits
Indium antimonide has the highest electron mobility and saturation velocity of any semiconductor, so has potential for ultra-high frequency operation with very low power dissipation. Unoptimised, uncooled quantum well heterojunction FETs, with gate length of 85nm, that have a cutoff frequency of 340GHz at only 0.5 V Vds. The prospects of this technology for future microwave applications in excess of 100GHz are shown to be very promising
