摘要：

We. investigated the twin domains of LaAlO3 (001) substrate using a scanning microwave microscope (SMM). Since the SMM can image the local dielectric constant of a sample quantitatively. we can observe the difference of the dielectric constant in the twin domains. Especially the (110) domains were observed more clearly than (100) domains. we attribute this to the difference of the strain in the ferroelastic LaAlO3.
