Each module contains 3 ECTS. You choose a total of 10 modules/30 ECTS in the following module categories:
- 12-15 ECTS in technical scientific modules (TSM)
TSM modules teach profile-specific specialist skills and supplement the decentralised specialisation modules.
- 9-12 ECTS in fundamental theoretical principles modules (FTP)
FTP modules deal with theoretical fundamentals such as higher mathematics, physics, information theory, chemistry, etc. They will teach more detailed, abstract scientific knowledge and help you to bridge the gap between abstraction and application that is so important for innovation.
- 6-9 ECTS in context modules (CM)
CM modules will impart additional skills in areas such as technology management, business administration, communication, project management, patent law, contract law, etc.
In the module description (download pdf) you find the entire language information per module divided into the following categories:
The students understand and are able to explain the basic principles of important engineering devices in relation to material properties and by applying microscopic concepts. These concepts include electrons and holes in solids, energy band structures of metals and semiconductors, polarization mechanisms in dielectrics and in piezoelectric materials, elementary dipole moments in magnetic materials and pairing of electrons in superconductors (Cooper pairs). Actual applications such as thermocouples, photovoltaic cells (solar cells), light emitting diodes (LED), piezoelectric actuators, magnetic sensors and data storage devices can be discussed by means of these concepts. This module will allow the students to understand modern concepts of prevailing technologies and use them in the future.
A solid knowledge of the fundamentals of physics is essential. Notions such as energy, force, thermal energy kBT, specific heat capacity, oscillations, resonance frequency, waves, electromagnetic field vectors: E, D, B and H, electric capacitance C, dielectric constant epsr and Bohr's model of atoms are mandatory. Also required are simple differential equations and complex numbers, in particular e-iwt.
