中文摘要 | algan/aln/gan/ingan/gan double heterojunction high electron mobility transistors (dh-hemts) structures with improved buffer isolation have been investigated. the structures were grown by mocvd on sapphire substrate. afm result of this structure shows a good surface morphology with the root-mean-square roughness (rms) of 0.196 nm for a scan area of 5 mu mx5 mu m. a mobility as high as 1950 cm(2)/vs with the sheet carrier density of 9.89x10(12) cm(-2) was obtained, which was about 50% higher than other results of similar structures which have been reported. average sheet resistance of 327 omega/sq was achieved. the hemts device using the materials was fabricated, and a maximum drain current density of 718.5 ma/mm, an extrinsic transconductance of 248 ms/mm, a current gain cutoff frequency of 16 ghz and a maximum frequency of oscillation 35 ghz were achieved. |
