  2. In the first step, effect of the target ' s components on properties of thin films was investigated. influences of tl2o partial pressure and thallination temperature on the component phases and properties of tl2ba2cacu2o8 hts thin films were studied in the second step of ex situ post annealing treatments

  3. 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。
