[Ifeffit] Build lower doping concentration structure in TKAtoms program.

Dear Prof: We have some questions about build lower doping concentration structure in TKAtoms program, as following; Q1: The TKATOM program can build up doping structure for lower doping concentration (below 10%) or not? Q2: If it can work, how should we build up the doping site? Q3: For lower doping case, how do these doped atoms choose where to go in TKATOM program, is it have physical description? ps: The attach ppt. file show more detail about our questions. Thanks for helping! Pei-chang Tsai ____________________________________________________________________________________ 怎樣減少垃圾信？只要看到垃圾信，立即按下「這是垃圾信」按鈕，垃圾信剋星幫助你清除你信箱垃圾。
