Semiconductor nanowires are an emerging class of materials with great potential for applications in future electronic devices. The small footprint and the large charge-carrier mobilities of nanowires make them potentially useful for applications with high- ...
This thesis aims at the site-specific realization of self-assembled field-effect transistors (FETs) based on semiconducting Zinc oxide NWs and their application towards chemical and bio-sensing in liquid medium. At first, a solution based growth method for ...
A charge carrier in the channel of an organic field-effect transistor (OFET) is coupled to the electric polarization of the gate in the form of a surface Fröhlich polaron [N. Kirova and M. N. Bussac, Phys. Rev. B 68, 235312 (2003)]. We study the effects of ...
Flexible transistors and circuits based on dinaphtho-[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT), a conjugated semiconductor with a large ionization potential (5.4 eV), are reported. The transistors have a mobility of 0.6 cm(2) V-1 s(-1) and the ring osci ...
Ferroelectric copolymers of polyvinylidene fluoride and trifluoroethylene are attractive gate materials because of a rather high remanent polarization, low dielectric permittivity, and easy integration on semiconductors due to the low processing temperatur ...
In organic thin-film transistors (OTFTs), the conducting channel is located near the interface between the organic semiconductor and the dielectric; this interface is crucial for transistor performance. The goal of this thesis is to study the effect of thi ...
In organic thin-film transistors (OTFTs), the conducting channel is located near the interface between the organic semiconductor and the oxide dielectric; this interface is crucial for transistor performance. Self-assembled monolayers (SAMs) on the interfa ...
Electronic devices based on organic semiconductors, such as field-effect transistors (OTFTs) and organic diodes have attracted significant interest as possible inexpensive and flexible alternatives to inorganic devices. Despite considerable improvement in ...
Organic thin-film transistors (TFTs) are of interest for applications that require electronic functionality with low or medium complexity distributed over large areas on unconventional substrates, such as flexible polymeric films. Generally these are appli ...
This thesis presents the fabrication and characterization of organic thin film transistors (TFTs) on flexible polymer substrates and the development of compliant stencil lithography to significantly improve the patterning resolution on full-wafer scale. Po ...
