    Abstract : A wide variety of novel complementary-metal-oxide-semiconductor (CMOS) devices that are strong contenders for future high-speed and low-noise RF circuits have been evaluated by means of static electrical measurements and low-frequency noise characterizations in this thesis. These novel field-effect transistors (FETs) include (i) compressively strained SiGe channel pMOSFETs, (ii) tensile strained Si nMOSFETs, (iii) MOSFETs with high-k gate dielectrics, (iv) metal gate and (v) silicon-on-insulator (SOI) devices.

    Abstract : The steady and aggressive downscaling of the physical dimensions of the conventional metal-oxide-semiconductor field-effect-transistor (MOSFET) has been the main driving force for the IC industry and information technology over the past decades. As the device dimensions approach the fundamental limits, novel double/trigate device architecture such as FinFET is needed to guarantee the ultimate downscaling. READ MORE

  7. 25. Vertical III-V Nanowire Tunnel Field-Effect Transistors : A Circuit Perspective

    Author : Gautham Rangasamy; Nanoelektronik; []

    Abstract : The energy scaling of integrated circuits has reached its limit because the operating voltage of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) based switches has reached its minimum value. MOSFETs are limited by thermionic emission and cannot achieve a subthreshold swing (SS) below 60 mV/decade at room temperature. READ MORE
