Organic semiconductors are promising materials for future electronic and electroluminescence applications. A detailed understanding of organic layers and nano-sized crystals down to single molecules can address fundamental questions of contacting organic s ...
We study the interfacial electronic properties of a model Si-SiO2-Si structure which is intended to simulate the substrate-oxide-polysilicon stack in metal-oxide-semiconductor devices. The structural properties of this model are shown to match closely thos ...
We present a theoretical study of the physical characteristics of metal/semiconductor junctions. Using first principle pseudopotential calculations, we have investigated the nature of electronic states with energies within the semiconductor band gap of rep ...
High-temperature superconductivity in copper oxides arises when a parent insulator compound is doped beyond some critical concentration; what exactly happens at this superconductor–insulator transition is a key open question1. The cleanest approach is to t ...
This thesis presents the results of a concerted effort to understand the complex array of physical properties exhibited by the BaVS3 family of materials. As a 3d1 system, BaVS3 displays a unique collection of correlation-driven phenomena, including a metal ...
Microcavity comprising two reflectors, at least one semiconductor layer separating said reflectors and a semiconductor quantum well wherein at least one of said reflectors and of said at least one semiconductor layer comprises a structure which is adjusted ...
Using plastics or dyes like molecular semiconductors to make optoelectronic devices at low cost is a project in industry that is of great interest to the "Information Community" of this beginning of the 21st century. Some applications of this technology ha ...
We discuss the spectral signatures of strong electronic correlations and electron-phonon interactions in two representative low-dimensional systems. In the 2D compound 1T-TaSe2 a charge-density-wave (CDW) induces a narrowing of the conduction band, which t ...
Scaling of semiconductor devices has pushed CMOS devices close to fundamental limits. The remarkable success story of Moore's law during the last 40 years, predicting the evolution of electronic device performances related to miniaturization, has always be ...
Nucleation and growth models are well developed for nucleation on homogeneous substrates, and they can typically be described-in terms of three energy parameters. Nucleation on substrates containing point-defect traps has been investigated, at the cost of ...
