Abstract:Laser-crystallization of amorphous $Ge_{0.85}Si_{0.15}$ films is studied, using green laser scanning and preformed topography to steer the crystallization. Large crystals (8x2 $\mu m^2$) are formed with location-controlled grain boundaries. The obtained films were characterized using Scanning Electron Microscopy, Transmission Electron Microscopy, Atomic Force Microscopy, X-Ray Photoelectron spectroscopy, X-Ray Diffraction and Spectroscopic Ellipsometry. In addition, the activation of ion-implanted poly- $Ge_{0.85}Si_{0.15}$ films is compared after furnace annealing, rapid thermal annealing and green-laser annealing
