| 英文摘要 | The electronic properties of hydrogen-saturated gan nanowires with different orientations and sizes are investigated using first principles calculations, and three types of nanowires oriented along the [0 0 1], [1 1 0] and [1 - 1 0] crystal directions are considered. the electronic properties of nanowires in all three directions are extremely similar. all the hydrogen-saturated gan nanowires show semiconducting behavior with a direct band gap larger than that of bulk wurtzite gan. quantum confinement leads to a decrease in the band gap of the nanowires with increasing nanowire size. the [0 0 1]-oriented nanowires with hexagonal cross sections are energetically more favorable than the [1 0 0]- and [1 -1 0]-oriented nanowires with triangular cross sections.
