The down-scaling of conventional MOSFETs has led to an impending power crisis, in which static power consumption is becoming too high. In order to improve the energy-efficiency of electronic circuits, small swing switches are interesting candidates to repl ...

We show that thin horizontal arrays of single wall carbon nanotubes (SWNTs) suspended above the channel of silicon MOSFETs can be used as vibrating gate electrodes. This new class of nano-electromechanical system (NEMS) combines the unique mechanical and e ...
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- ...
Uniform, 2 nm diameter gold nanowires were synthesized through the reduction of gold(III) chloride in an oleylamine matrix. They were top-contacted on a Si/SiO2 substrate with metallic electrodes to manufacture back-gated transistors. Due to thermal breaka ...
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 ...
Technology scaling improves the energy, performance, and area of the digital circuits. With further scaling into sub-45nm regime, we are moving toward very low supply (VDD) and threshold voltages (VT), smaller VDD/VT ratio, high leakage current, and large ...

We have investigated an inductively coupled plasma etching recipe using SiCl4 and SF6 with a resulting selectivity >10 for GaN in respect to InAlN. The formation of an etch-resistant layer of AlF3 on InAlN required about 1 min and was noticed by a 4-times- ...
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 ...
We report on an annealing-induced "gate sinking" effect in a 2-nm-thin In0.17Al0.83N/AlN barrier high electron mobility transistor with Ir gate. Investigations by transmission electron microscopy linked the effect to an oxygen containing interlayer between ...
This work demonstrates a method for incorporating strain in silicon nanowire gate-all-around (GAA) n-MOSFETs by oxidation-induced bending of the nanowire channel and reports on the resulting improvement in device performance. The variation in strain measur ...
