2022年10月17日 · Here, we design a high-throughput PVD method to synthesize 2D p-doped SnSe on mica in a controlled manner. A metallic feature is uncovered in 2D p-doped SnSe due to the local phase...

2023年2月14日 · High-quality 2D ferroelectric SnSe is synthesized by low-pressure physical vapor deposition. To achieve large-sized ultrathin SnSe, effects of substrate pre-annealing, growth duration, temperature, a...

2022年4月12日 · The 2D surface facets of SnSe benefit for the formation and stabilization of LiO 2 intermediates, leading to the efficient formation/decomposition of discharge products. The findings provide in-depth insight into the elusive electrocatalytic mechanism for 2D layer-structures materials in LOBs.

Here, we report the growth of complex 2D nanonetworks of crystalline tin selenide (SnSe) via liquid injection chemical vapor deposition using a single-source diselenoether precursor. Potential applications of SnSe span a wide range of technological areas, particularly in energy devices.

2024年8月12日 · We use the in situ photoluminescence (PL) technique to investigate the role of 2D materials in the crystallization process. The results show that SnSe nanosheets primarily shorten the grain boundary merging time and reduce the defect generation during the grain boundary merging stage, thereby regulating the crystallization of perovskite.

2024年7月5日 · Here, a TS device based on two-dimensional (2D) SnSe is demonstrated. Owing to the diffusive dynamics of Ag ions in SnSe, intrinsic stochasticity of the TS behavior is observed, which can be exploited to construct a compact stochastic Leaky-Integrate and Fire (LIF) model with improved performance in spiking neuron network (SNN).

2023年6月15日 · Here, two sets of 2D/2D SnS 2 /SnSe 2 vdW heterostructures with tunable SnSe 2 content are fabricated by physical mixing and solvothermal growth methods for room-temperature NO 2 gas sensors. Compared to pure SnS 2 and SnSe 2 layers, the creation of 2D/2D vdW heterostructure shows a great improvement in sensing performance at …

2024年6月1日 · In summary, we confirmed that Bi doping can enhance the ferroelectricity of 2D layered SnSe thin by using the PFM and the neuromorphic memristor based on 2D ferroelectric Sn 1-x Bi x Se can simultaneously sense, process, and store in situ to achieve a variety of functions under optical and electrical fields.
