Via Vetoio 10, 67100 L’ Aquila, Italy e-mail: [email protected] The discovery of novel properties, effects or microscopic mechanisms in modern materials science is often driven by the quest for combining, into a single compound, several functionalities: not only the juxtaposition of the latter functionalities, but especially their coupling, can open new horizons in basic condensed matt...

The utilisation of crystalline semiconductor materials as detectors and devices operating in high radiation environments, at the future particle colliders, in space applications, in medicine and industry, makes necessary to obtain radiation harder materials. Diamond, SiC and different A III B V compounds (GaAs, GaP, InP, InAs, InSb) are possible competitors for silicon to different electronic d...

The scale of environmental impacts associated with the manufacture of microchips is characterized through analysis of material and energy inputs into processes in the production chain. The total weight of secondary fossil fuel and chemical inputs to produce and use a single 2-gram 32MB DRAM chip are estimated at 1600 g and 72 g, respectively. Use of water and elemental gases (mainly N2) in the ...

Phthalocyanines and their main group and metal complexes are important classes of organic semiconductor materials but are usually highly insoluble and so frequently need to be processed by vacuum deposition in devices. We report two highly soluble silicon phthalocyanine (SiPc) diester compounds and demonstrate their potential as organic semiconductor materials. Near-infrared (λ(EL) = 698-709 nm...

Almost ever since the advent of the microelectronics adventure, silicon-based MOSFET (metal–oxide–semiconductor fieldeffect transistor) technology has been largely dominant. However, for a few years now this technology has exhibited some fundamental limitations in tackling the increasingly challenging issues of miniaturization and improvements in processing speed and power consumption. Hence, n...

The feasibility of creating and manipulating coherent quantum states on surfaces of functionalized semiconductor nanostructures is computationally investigated. Quantum dynamics simulations of electron-hole transfer between catechol molecules adsorbed on TiO2 -anatase nanostructures under cryogenic and vacuum conditions indicate that laser induced coherent excitations can be prepared and manipu...

rapid thermal processing (rtp) has become a key technology for semiconductor device manufacturing in a variety of applications, such as thermal oxidation, annealing, and thin-film growth. hence, understanding the radiative properties of silicon and other relevant materials is essential for the analysis of the thermal transport processes. we have analyzed and calculated the spectral, directional...

Light in certain engineered dielectric microstructures can flow in a way similar to electrical currents in semiconductor chips. These microstructures represent a new frontier in the field of optics. They provide a foundation for the development of novel micro-photonic devices and the integration of such devices into an optical microchip. Glossary: Photonics: the science of moulding the flow of ...
