The electrical properties of SrTiO_3 are strongly dependent on the oxygen vacancy concentration. Using Ar~+ bombardment can cause oxygen vacancy on the surface of SrTiO_3. This paper proposed a method based on Monte Carlo simulation to controlion implantation time. The movement of Ar~+ after being implanted into SrTiO_3 was simulated by using SRIM process. The distribution of oxygen vacancy was analyzed, and through iterative calculation the relation ship between the oxygen vacancy concentration and the tim...

由于计算机模拟实验方法相对成本低、易操有MORSE、EGS、SRIM等。SRIM作为一套开源作、变化范围大,所以计算机模拟得到广泛运用。的离子注入模拟软件,是目前模拟离子注入运用最计算机模拟离子注入主要包括分子动力学和蒙特卡广泛的。SRIM (The Stopping and Range of Ions in罗
