Electrical engineering is dominated in fundamental research and applications by microelectronics and nanoelectronics using semiconductor materials with a high purity. The manufacture of these materials – e.g. magnetic field-controlled floating-zone single crystal growth process for the production of pure silicon ingots – and the functionality of electronic semiconductor devices (e.g. CMOS transistors and other devices) are based on physical phenomena concerning the surfaces and interfaces of materials. Modelling these physical processes at the surfaces and interfaces requires profound knowledge of material sciences and semiconductor physics in particular. Furthermore, the simulation of material surfaces and physical interfaces requires the solution of multiscale problems that need sophisticated mathematical methods. Important applications include Micro-Electro-Mechanical-Systems (MEMS) and Nano-Electro-Mechanical Systems (NEMS).
