| 中文摘要 | metamorphic high electron mobility transistor (m-hemt) structures have been grown on gaas substrates by molecular beam epitaxy (mbe). linearly graded and the step-graded ingaas and inalas buffet layers hal e been compared, and tem, pl and low-temperature hall have been used to analyze the properties of the buffer layers and the m-hemt structure. for a single-delta-doped m-hemt structure with an in0.53ga0.47as channel layer and a 0.8 mum step-graded inalas buffer layer, room-temperature mobility of 9000 cm(2)/v s and a sheet electron density as high as 3.6 x 10(12)/cm(2) are obtained. these results are nearly equivalent to those obtained for the same structure grown on an inp substrate. a basic m-hemt device with 1 mum gate was fabricated, and g(m) is larger than 400 ms/mm.
