Ebeling for providing me with the possibilityto perform this work under his supervision in a (both scientifically and personally)excellently suited environment. I would also like to thank him explicitly for motivatingme to finish in due time.Naturally, I also owe a lot to everybody in the Optoelectronics Department, especiallythe guys in room 45.2.217. For scientific help and discussions I would like to specificallythank Rainer Michalzik, Jurgen¨ M¨ahnß and Wolfgang Schmid.
