Non-Planar Vertical Photodetectors Based on Free-Standing Two-Dimensional SnS2 Nanosheets

Abstract

The development trend of modern electronics and optoelectronics is toward the continuous high integration and miniaturization. Vertical configurations with three dimensional geometry are facile to constitute higher integration density than the tranditional planar one, thus holding great promising for designing next-generation electronics/optoelectronic devices. Two-dimensional layered metal dichalcogenides (2D-LMDs) are important building blocks for electronics/optoelectronic devices, whereas they are usually parallel growth to the substrates during chemical vapor deposition (CVD), consequently determining they are solely exploited to fabricate lateral structure devices with planar geometry. Herein, we for the first time realized the vertical growth of free-standing 2D layered nanosheets of hexagonal tin disulfide (SnS2) on flat substrate via a modified CVD method. Furthermore, we successfully demonstrated our first try to fabricate kind non-planar vertical photodetectors using our free-standing SnS2 nanosheets for promising photodetection applications. This work paves the way for growth monodisperse vertical 2D-LMDs nanosheets on flat substrates, and expands their utilizations from conventional lateral structured devices to non-planar vertical electronics/optoelectronic devices.
