Valley splitting theory of SiGe/Si/SiGe quantum wells
We present an effective mass theory for SiGe/Si/SiGe quantum wells, with an emphasis on calculating the valley splitting. The theory introduces a valley coupling parameter vv which encapsulates the physics of the quantum well interface. The new effective mass parameter is computed by means of a tight binding theory. The resulting formalism provides rather simple analytical results for several g...
متن کاملDopant diffusion in Si and SiGe
Dopant diffusion in semiconductors is an interesting phenomenon from both technological and scientific points of view. Firstly, dopant diffusion is taking place during most of the steps in electronic device fabrication and, secondly, diffusion is related to fundamental properties of the semiconductor, often controlled by intrinsic point defects: self-interstitials and vacancies. This thesis inv...
متن کاملSi and SiGe Millimeter-Wave Integrated Circuits
Monolithic integrated millimeter-wave circuits based on silicon and SiGe are emerging as an attractive option in the field of millimeter-wave communications and millimeterwave sensorics. The combination of active devices with passive planar structures, including also antenna elements, allows single-chip realizations of complete millimeter-wave front-ends. This paper reviews the state-of-the-art...
متن کاملA programmable CMOS bandgap voltage reference circuit using current conveyor
This paper presents a new structure of a bandgap circuit which can be programmed to get any desired output voltage. Unlike conventional bandgap circuits, the proposed bandgap circuit uses MOS transistors operating in subthreshold region instead of bipolar transistors to generate PTAT and IPTAT currents. Use of the current conveyor makes the circuit capable of being operated at lower supply volt...
متن کاملA comparison of thin film microrefrigerators based on Si/SiGe superlattice and bulk SiGe
Most of the conventional thermal management techniques can be used to cool the whole chip. Since thermal design requirements are mostly driven by the peak temperatures, reducing or eliminating hot spots could alleviate the design requirements for the whole package. Monolithic solid-state microcoolers offer an attractive way to eliminate hot spots. In this paper, we review theoretical and experi...
