We measured the samples " electrical properties ( square resistance, square carrier concentration, carrier mobility and hall coefficient ) at room temperature by hall measurement. the experimental results revealed that all the samples are p - type, with increasing the annealing temperature, the carrier mobility increased and the square carrier concentration decreased. these changes in electrical properties are explained by a decrease in the number of mn acceptors because of the forming of mnas phase and the resuming of lattice defects during annealing
所有樣品均為p型導電類型；發現在650到850溫度范圍內，隨著退火溫度的升高，樣品的方塊載流子濃度呈下降趨勢，而載流子遷移率呈上升趨勢；這是由於在退火過程中，隨著退火溫度的升高，有更多的mn參與mnas相的形成，使得以替位受主形式存在的mn減少，並且晶格缺陷得到恢復所致。 -

Experimental results revealed that the carrier mobility increased with increasing of the annealing temperature, in the range of the annealing temperature from 650 ? to 850 ?, which implied that the crystal lattice structure was damaged by ion implantation and restored after annealing. furthermore, the square carrier concentration decreased, and the square resistance of the samples implanted by mn + and c increased with the raising of annealing temperature. these results indicated that the second phase such as mnga, mnas ferromagnets was formed by more mn + ions with increasing of the ( gaas ) annealing temperature, so the mn + ions which can provide carriers decreased
由實驗結果可以知道在退火溫度為650 850范圍內，樣品的載流子遷移率隨著退火溫度的提高呈上升趨勢，說明雜質元素的注入對樣品造成晶格損傷，但退火對這些損傷具有修復作用；此外，隨著退火溫度的上升，樣品的方塊載流子濃度不斷下降，加c樣品的方塊電阻不斷上升，這都是因為隨著退火溫度的提高，摻入的mn ~ +離子不再提供載流子，而是形成了mnga 、 mnas等磁性第二相。 -
