6. Heterostructure Field Effect Transistors and Millimeter Wave Integrated Circuits
Sammanfattning : This thesis deals with the research and development of HFETs and HFET based circuits. One of the main aims of the work presented in this thesis has been to develop processes to fabricate state of the art devices and circuits. LÄS MER
7. Exposure, telomere length, and cancer risk
Sammanfattning : Telomeres are tandem repeats of TTAGGG at the end of eukaryotic chromosomes. Telomeres play a key role in chromosome stability and regulation of the cellular lifespan. Telomeres are shortened during cell division, and probably, by not yet well characterised factors in the environment. LÄS MER
8. Charge carrier transport in field-effect transistors with two-dimensional electron gas channels studied using geometrical magnetoresistance effect
Sammanfattning : During the last decades, significant efforts have been made to exploit the excellent and promising electronic properties exhibited by field-effect transistors (FETs) with two-dimensional electron gas (2DEG) channels. The most prominent representatives of this class of devices are high-electron-mobility transistors (HEMTs) and graphene field-effect transistors (GFETs). LÄS MER
9. Effect of estrogen on longitudinal bone growth
Sammanfattning : Longitudinal bone growth occurs at the growth plate, a thin layer of cartilage between the epiphysis and the metaphysis of long bones. In the growth plate resting chondrocytes proliferate, differentiate into a hypertrophic form, and finally become terminal hypertrophic chondrocytes before giving rise to bone. LÄS MER
10. Investigations of Diesel Sprays in Optical Engines - Liquid Fuel Penetration and Lift-Off Length
Sammanfattning : Diesel engines are widely used as powertrain solutions for transportation vehicles. Their low fuel consumption and high performance make them attractive, however, their associated pollutant emissions is a major drawback which represent a hazard for public health and the environment.
