2021年8月20日 · Here the authors use a one-step hydrothermal approach to synthesis WS2 moiré superlattices with high catalytic activity for hydrogen evolution reaction

2024年2月10日 · The higher stability of thinner 2M WS2 is attributed to stiffened intralayer bonds, enhanced thermal conductivity and higher average barrier per layer during the layer(s)-by-layer(s) phase ...

HRTEM analysis reveals epitaxial growth of thin layered, hexagonal WS 2 on RGO (Fig. 2g, h and Supplementary Information S3). HRTEM analysis near the edge of the WS 2 sheets shows an...

2019年1月19日 · The microstructures and elemental mappings recorded by energy dispersive X-ray spectroscopy (EDS) were conducted on a high-resolution transmission electron microscope (HRTEM, JEM 2010F) at 200 kV acceleration voltage.

Closed capped WS 2 nanotubes with diameters from 30 to 110 nm are studied by high resolution transmission electron microscopy (HRTEM). The tubes exhibit preferentially a hexagonal stacking order. Atomic resolution images of a 30 nm diameter tube reveal a zigzag chirality.

2023年1月15日 · Benefiting the unique multichannel carbon nanostructure as a current collector-integrated electrode as well as mixed-phase lamellar structure WS 2 for enhanced potassium ion entry, the 1T/2H-WS 2 / N -MCNFs hybrid current-collector-free anode delivers an outstanding areal capacity of 2.88 mAh cm −2 (corresponding to 411 mAh/g based on the mass o...

2 天之前 · Fig. 3 b and 3c show the HRTEM images of monolayer WS 2 and MoS 2 regions, respectively, both of which exhibit pristine hexagonal lattices. ... (X WS2) and MoS 2 (X MoS2), respectively. Their exciton lifetimes are extracted and summarized in Fig. 4 d. It can be seen that the excitons at different positions have different lifetimes, and those at ...

Centimeter-scale continuous monolayer WS2 film with large tensile strain has been successfully grown on oxidized silicon substrate by chemical vapor deposition (CVD), in which monolayer grains...

2011年11月1日 · Closed capped WS2 nanotubes with diameters from 30 to 110 nm are studied by high resolution transmission electron microscopy (HRTEM). The tubes exhibit preferentially a hexagonal stacking...

第一种条件下，ws2的hrtem显示竖直的结构，可以看到条纹状图案，条纹间距是0.62nm左右，但是这时候的拉曼光谱并没有显示出ws2的振动峰。 第二种条件下，WS2的HRTEM显示是平面结构，但是间距是0.35nm好像，跟卡片数据对不上来；
