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 ...
We review the current hopes for applications of exciton-polaritons in semiconductor microcavities. These quasi-particles have become distinguished in recent years for a variety of different effects including Bose-Einstein condensation, ballistic spin curre ...
Multicast parametric synchronous sampling (MPASS) architecture for real-time processing of optical signals based on parametric processes is reviewed. The processor uses parametric gates to obtain multiple sub-rate outputs. Operating principle and first dem ...
Silicon technology has advanced at exponential rates both in performances and productivity through the past four decades. However the limit of CMOS technology seems to be closer and closer and in the future we might see an increasing number of hybrid appro ...
Microcavity exciton-polaritons are half-matter half-light quasiparticles with outstanding properties. This offers a great way to access and control fundamental excitations in a solid by simple optical means. Therefore, apart from their importance in fundam ...
The ubiquitous role occupied by optical fibres in modern photonic systems has steadily stimulated research to realize slow and fast light devices directly in this close-to-perfect transmission line. This potentially offers the key advantage of a direct and ...
An important prerequisite for the design of digital integrated circuits is the ability to control the threshold voltage of the individual transistors during manufacturing. To address the problem of controlling the threshold voltage of low-voltage organic t ...
Interest in PVDF-TrFE copolymers as ferroelectric material for Memory application is driven by the prospect of having low cost, low operating voltage and fully organic device. Some previous studies reported FET designs using copolymers [refs 1,2] but none ...
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 an optofluidic photoswitchable grating, based on a polydimethylsiloxane periodic structure on a glass substrate, separated by a thin liquid crystal film. The polydimethylsiloxane microstructure was realized via high resolution replica molding and ...
