Keywords:SnS, PFM, polarization domain

We have reported research of ferroelectricity and bulk photovoltaic effect of SnS. It is generally difficult to observe in-plane polarization domain of SnS by PFM because output of PFM is small. In this research, We succeeded in the observation and considered crystal structure with lateral-PFM images.
