摘要: A normally-off transistor includes a first region of III-V semiconductor material, a second region of III-V semiconductor material on the first region, a third region of III-V semiconductor material on the second region and a gate electrode adjacent at least one sidewall of the third region. The first region provides a channel of the transistor. The second region has a band gap greater than the band gap of the first region and causes a 2-D electron gas (2DEG) in the channel. The second region is interposed between the first region and the third region. The third region provides a gate of the transistor and has a thickness sufficient to deplete the 2DEG in the channel so that the transistor has a positive threshold voltage.
