Biosensoren auf der Basis von Halbleiter-Feldeffektstrukturen mit angekoppelten Insektenantennen
The main goal of this work was the realization of a biosensor for the detection of small concentrations of organic odor substances by means of coupling an insect antenna to a field-effect transistor. A sensor concept based on a BioFET (biologically sensitive field-effect transistor) was developed, …

Physical studies of strained Si/SiGe heterostructures : from virtual substrates to nanodevices
During the past two decades, the decrease in intrinsic delay of MOSFETs has been driven by the scaling of the device dimensions. The performance improvement has relied mostly in the increase of source velocity with gate scaling, while the transport properties of the channel have remained constant, …

Selbstorganisation von Kohlenstoffnanoröhren zu Feldeffekttransistoren
… nach der Deposition ist es gelungen, CNT-Feldeffekttransistoren (CNT-FETs) mit Schaltverhältnissen von bis zu sieben Dekaden herzustellen. Auch dieses Verfahren ist skalierbar und unkompliziert, da es sich selbst steuert. Es ist skalierbar und deshalb auch für technische Anwendungen …

Physical investigations of novel materials and structures for Nano-MOSFETs
In this thesis four important physical and material aspects faced by MOSFET devices as dimensions move to the length scale of 10nm have been investigated: i) metal source/drain contacts with dopant segregation for reduced contact resistance and improved carrier injection; ii) variability of the …

Primary neuronal culture of Locusta migratoria for construction of networks on microelectronic recording devices
In this thesis a basis for the construction of simple neuronal networks of Locusta migratoria was developed. For the study of synaptogenesis and signal transmission over a long time period and at many recording sites simultaneously, it is desired to couple those networks with extracellular …

Scaling of the ferroelectric field effect transistor and programming concepts for non-volatile memory applications
The importance of non-volatile memory for storage of digital information is without question. Research over the years has led to many different types of memory, each tailored to a specific need. Always, however, the search has continued for a universal type that combines high speed operation with …

Transistor arrays for the direct interfacing with electrogenic cells
In this work, a floating gate field effect transistor (FET) for the coupling of electrogenic cells was presented. The design decoupled the transistor gate from the sensing area and arranged them one upon the other (sandwich design). Both parts were tuned individually: the transistors were optimised …

Phasenkohärenter Transport und Spin-Bahn-Wechselwirkung in III/V-Halbleiternanodrähten
Semiconductor nanowires fabricated by a bottom-up approach are not only interesting for the realization of future nanoscaled devices but also appear to be very attractive model systems to tackle fundamental questions concerning the transport in strongly confined systems. In order to avoid the …
