MoS 2 and WS 2 micro- and nanotubes prepared by chemical transport reaction grow by spiral rolling of the molecular layers up to few millimetres in length and up to several micrometers in diameter. Each rolling molecular layer has to satisfy the stacking order and orientation relationship regarding the previous layer. Therefore, the strain appears in the tube walls, which relaxes in...
We present original scanning tunnelling microscope (STM) images of the first growth stages of crystalline, textured WS 2-x thin films (x = 0.2-0.4) prepared by reactive RF magnetron sputtering. In the first 10-20 nm of thickness, the films grow in the shape of trigonal pyramids with typical lateral size in the 20 nm range. Step heights of 0.6 nm show that the films grow by molecular...
