Tin selenide (SnSe) is a layered monochalcogenide that will exhibit piezoelectricity, and potentially ferroelectricity, when scaled to the monolayer limit. Part of the difficulty in assessing ferroelectricity in SnSe stems from the relatively strong van der Waals bonds that make it difficult to isolate a monolayer using conventional mechanical exfoliation. Therefore, processing routes that simultaneously allow for the control of the layer number, stoichiometry, crystallographic orientation, and grain size are critically needed for SnSe. This work investigates the impact of flux ratio on the stoichiometry of SnSe thin films deposited via molecular beam epitaxy (MBE). The substrate preparation methods, like cleaving and vacuum annealing, will also be discussed with respect to the impact on the in-plane orientation and planar growth of the SnSe thin films. Finally, a method is proposed to assess the presence of ferroelectricity and the mechanisms that drive ferroelectric switching in this material.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\u003Cul type=\u0022disc\u0022\u003E\u003Cli\u003EProfessor Lauren M.
