用卢瑟福背散射/沟道(RBS/Channeling)技术研究了在Al2O3(0001)衬底上用MOCVD方法生长的ZnO薄膜的弹性应变。ZnO薄膜的χmin=5.1%
表明其具有非常好的结晶品质。ZnO薄膜的四方畸变为正
表明其在水平方向是拉应变
垂直方向是压应变。弹性应变由界面向表面逐渐释放
其在界面附近最大
在表面处最小。
The elastic strain of ZnO film
grown on Al2O3(0001) substrate by MOCVD
was studied by RBS/Channeling. Its χmin is 5.1%
which shows that ZnO film has very high crystal quality. The positive tetragonal distortion indicates that pull strain in the horizontal direction and press strain in the vertical direction happen. The elastic strain is gradually released from interface to surface. In the interface
the elastic strain is the maximum
while in the suface
it is the minimum.
