Abstract :
AlSb polycrystalline thin films were prepared by cosputtering. The structure, morphology and electrical properties of the films are studied. X-ray diffraction results show that the films are AlSb polycrystalline with a face-centered cubic structure. The use of hydrogen in the atmosphere and the higher substrate temperature are beneficial to the grain growth of the AlSb films. The intrinsic AlSb film is p-type semiconductor with the conductivity activation energy of 0.32 eV and 0.25 eV.
