Abstract :
[en] We report on the dc and RF performance of HEMT’s based on the Al-free material system InP/InGaAs/InP. These structures were grown by LP-MOCVD using a nitrogen carrier. The influence of gate length and channel composition on the performance of these devices is investigated.We demonstrate that optimum dc and RF performance using highly strained channels can be obtained only if additional composite channels are grown. The cutoff frequencies fT =160 GHz and fmax=260 GHz for a 0.1- um T-gate device indicate the suitability of our devices for W-Band applications.
