Title

Epitaxial Electrodeposition of Tin(II) Sulfide Nanodisks on Single-crystal Au(100)

Abstract

Epitaxial nanodisks of tin(II) sulfide (SnS) are deposited electrochemically on a [100]-oriented single-crystal Au substrate from an acidic solution at 70 °C. The SnS grows with two different out-of-plane orientations of [100] and [301], which each have four equivalent in-plane orientations. X-ray pole figures reveal the following epitaxial relationships: SnS(100)[010]//Au(100)[010], SnS(100)[010]//Au(100)[01̅0], SnS(100)[010]//Au(100)[001], SnS(100)[010]//Au(100)[001̅], SnS(301)[010]//Au(100)[010], SnS(301)[010]//Au(100)[01̅0], SnS(301)[010]//Au(100)[001], and SnS(301)[010]//Au(100)[001̅]. For the SnS[100] orientation, the in-plane mismatch is −2.4% in the [010] direction and 6.1% in the [001] direction. For the [301] orientation, the in-plane mismatch is −2.4% in the [010] direction and alternates between 3.4% and 6.7% in the [103̅] direction. The SnS deposits with a disklike morphology with a diameter of 300 nm and a thickness of 50 nm.
