Basic scientific research has continuously provided an increasingly comprehensive insight into the structure of matter and our understanding of creation of universe. At the same time, the new insights generated many technical developments and applications. The bigger part of the insights attained has been all because of our advanced accelerator facilities. The accelerator facility is a key instrument for research at GSI Darmstadt, Germany and it is different and unique in many aspects to all other accelerators facility in the world. One of the main nuclear physical basic researches at GSI is the study of hot and dense nuclear matter. With heavy ion beams, the multiple varieties of nuclear matter, from the "liquid" normal state over the free nucleon gas, to the disintegration of the nuclear components into quark-gluon plasma, can be studied. Compressed Baryonic Matter (CBM) Experiment is dealing with that area of research. This book will give a fundamentals of semiconductor physics and Silicon detector physics and its application and characterization using dedicated and specialized instruments. A detailed analysis of experimental test is showing how these detectors really operate.
