Preface This volume contains the manuscripts submitted for the Proceedings of the 16th International Conference on "Gettering and Defect Engineering in Semiconductor Technology - GADEST 2015" held from September 20th to 25th in Bad Staffelstein, Germany.
From its beginning, it was intended as an international forum for experts in the field of semiconductor technology, semiconductor device physics and defect physics with participants from academia as well as from industry.
Because the proceedings are distributed at the conference, an early deadline had to be met. 71 manuscripts were submitted until then and organized into the following chapters:  Growth of Mono- and Multi-Crystalline Silicon  Passivation and Defect Studies in Solar Cells  Intrinsic Point Defects and Dislocations in Silicon  Light Elements in Silicon-Based Materials  Properties and Gettering of Transition Metals in Silicon  Radiation- and Impurity-Related Defect Studies in Silicon and Germanium  Thermal Properties of Semiconductors  Luminescence and Optical Properties of Semiconductors  Nano-Sized Layers and Structures  Wide-Bandgap Semiconductors  Advanced Methods and Tools for Investigation of Semiconductor Materials The papers were directly reproduced from the manuscripts submitted by the authors.
