Growth and properties of the CuInS2 thin films produced by glancing angle deposition

摘要: Abstract We use the glancing angle deposition technique (GLAD) to grow CuInS2 thin films by a vacuum thermal method onto glass substrates. During deposition, substrate temperature was maintained at 200 °C. Due shadowing effect oblique can produce nanorods tilted toward incident flux. The evaporated atoms arrive growing interface fixed θ measured from normal. is rotated with rotational speed ω 0.033 rev s− 1. show that of this growth leads an improvement in optical properties films. Indeed high absorption coefficients (105–3.105 cm− 1) visible range and near-IR spectral are reached. In case absence rotation, scanning electron microscopy pictures structure resulting film consists nanocolumns progressively inclined towards evaporation source as increased. If rapid azimuthal rotation accompanies tilt, nanostructure composed array pillars normal substrate. surface morphology without presence secondary phases for higher angles (θ > 60°).
