System and method for removing scalloping and tapering effects in high aspect ratio through-silicon vias of wafers

Edoardo Charbon, Sandro Carrara, Simone Frasca

A method for manufacturing vias in a silicon wafer, the silicon wafer having a crystal orientation, and having a plane that is perpendicular to a surface of the wafer, tilted by 35.26°, the method comprising the steps of providing a mask having ...

Crystallographically Oriented Hybrid Perovskites via Thermal Vacuum Codeposition

Mohammad Khaja Nazeeruddin, Mounir Driss Mensi, Hiroyuki Kanda, Cristina Roldán Carmona, Nadja Isabelle Desiree Klipfel, Cheng Liu

Hybrid lead halide perovskites typically form polycrystalline films that have multiple grain sizes and surface defects. A key engineering challenge toward commercialization is therefore the production of homogeneous, defect-free largearea devices achieving ...

Cluster Catalysis with Lattice Oxygen: Tracing Oxygen Transport from a Magnetite (001) Support onto Small Pt Clusters

Wolfgang Harbich, Giulia Elisabetta Pacchioni, Ke Zhang

Oxidation catalysis on reducible oxide-supported small metal clusters often involves lattice oxygen. The present work aims at differentiating whether the reaction takes place at the cluster/support interface or on the cluster. To that purpose, we trace the ...
