中文摘要 | a novel algan/gan/gan/gan double heterojunction high electron mobility transistors (dh-hemts) structure with an aln interlayer on sapphire substrate has been grown by mocvd. the structure featured a 6-10 nm in0.1ga0.9n layer inserted between the gan channel and gan buffer. and wer also inserted one ultrathin. aln interlayer into the al/gan/gan interface, which significantly enhanced the mobility of two-dimensional electron gas (2deg) existed in the gan channel. afm result of this structure shows a good surface morphology and a low dislocation density, with the root-mean-square roughness (rms) of 0.196 nm for a scan area of 5 mu m x 5 mu m. temperature dependent hall measurement was performed on this sample, and a mobility as high as 1950 cm(2)/vs at room temperature (rt) was obtained. the sheet carrier density was 9.89 x10(12) cm(2), and average sheet resistance of 327 omega/sq was achieved. the mobility obtained in this paper is about 50% higher than other results of similar structures which have been reported.
