Aim
Modern electronics such as mobile- and satellite-based communication systems are based on the performance of high-speed devices. This course covers the fundamental design of the heterostructures in key devices within established and emerging technologies. It contains basic modelling of DC and AC properties for HBTs and FETs, but also specific nano electronic applications such as tunnel diodes and ballistic FETs. The lectures are based on a mathematical description of the transport properties within the devices, while state-of-the-art performance devices will be presented as examples.
