11. Novel concepts for advanced CMOS : Materials, process and device architecture
Abstract : The continuous and aggressive dimensional miniaturization ofthe conventional complementary-metal-oxide semiconductor (CMOS)architecture has been the main impetus for the vast growth ofIC industry over the past decades. As the CMOS downscalingapproaches the fundamental limits, unconventional materials andnovel device architectures are required in order to guaranteethe ultimate scaling in device dimensions and maintain theperformance gain expected from the scaling.

12. Charge carrier traffic at interfaces in nanoeletronic structures
Abstract : This thesis describes investigations in relation to the search for materials with high dielectric constant, k, for future CMOS transistors. The most elementary quantities to be considered are k-value and energy band offsets between the dielectric and the silicon crystal on which it is deposited. READ MORE

13. Vertical Nanowire High-Frequency Transistors
Abstract : This thesis explores a novel transistor technology based on vertical InAs nanowires, which could be considered both for low-power high-frequency analog applications and for replacing Si CMOS in the continued scaling of digital electronics. The potential of this device - the vertical InAs nanowire MOSFET – lies in the combination of the outstanding transport properties of InAs and the improved electrostatic control of the gate-all-around geometry.
