Equipmen: AFM Bruker Dimension Edge Responsible research: Dr. Francisco Flores Day: 1 First training day on AFM Bruker Dimension Edge AFM at the Physics Institute of BUAP. This equipment will allow the measurement of topography properties like roughness and grain size. The researcher in charge explains too that it's possible to acquire electrical conductivity and work function from the surface of the films.

Location: Physics Institute of BUAP, Puebla, Pue. Chemical deposition: Bi2S3 Bismuth Sulfide Supervisor: M.C Denisse Loeza Chemical deposition of bismuth sulfide from the master thesis work of M.C. Denisse Loeza. This work has the intention to develop new materials (semiconductors) for solar cells. Like the ternary compound Cu3BiS3, which posses potential properties as a p-type semiconductor for absorber layer on thin-film technology.
