| dc.description.abstractEn | Photoactive thin films of WS2 have been prepared by radio frequency magnetron sputtering. Physico-chemical properties of the films are mainly investigated by Rutherford backscattering and X-ray diffraction. Optical and transport properties are also studied. Films sputtered at a high substrate temperature are made of small bidimensional grains (2H–WS2) surrounded by amorphous boundaries. The photoactivity of these films is weak because of the electron trapping at boundaries. Films sputtered at a low substrate temperature are amorphous and then annealed to produce bidimensional films. It is shown that annealed Ni-coated films give highly textured samples. A nickel–sulphur phase is assumed to act as a surfactant. The strong photoactivity enhancement of these films is attributed to an increase in the grain size. | |
