Architecture for integrated RF photonic downconversion of electronic signals

Electronic analog to digital converters (ADCs) are run-ning up against the well-known bit depth versus bandwidth trade off. Towards this end, radio frequency (RF) photonic-enhanced ADCs have been the subject of interest for some time. Optical frequency com ...

Tuning paradigm of external stimuli driven electronic, optical and magnetic properties in hybrid perovskites and metalorganic complexes br

Mohammad Khaja Nazeeruddin

We have witnessed a wide range of theoretical as well as experimental investigations to envisage external stimuli induced changes in electronic, optical and magnetic properties in the metal organiccomplexes, while hybrid perovskites have recently joined th ...

Accuracy of Molecular Simulation-Based Predictions of k(off) Values: A Metadynamics Study

Ursula Röthlisberger, Simone Meloni, Viacheslav Bolnykh, Michele Parrinello, Paolo Carloni

The k(off) values of ligands unbinding to proteins are key parameters for drug discovery. Their predictions based on molecular simulation may under- or overestimate experiment in a system- and/or technique-dependent way. Here we use an established method-i ...

Template-assisted grown III-V semiconductor nanowires: A transmission electron microscopy study

Nicolas Bologna

III-V semiconductor nanowires are, due to their unique properties, one of the most promising nanostructures developed in the last decades. However, the realization of commercial devices made of III-V nanowires, such as transistors and solar cells, has not ...

Construction of a low temperature STM and studies of large molecular systems

Daniel Pablo Rosenblatt

Several aspects in the field of molecular self assembly are addressed in this thesis. Thanks to the scanning tunnelling microscope (STM), structural, electronic and magnetic properties on surfaces can be studied down to the size of a single atom. In this t ...

Nanostructure Symmetry: Relevance for Physics and Computing

Marc-André Dupertuis, Daniel Oberli, Sascha Dalessi, Benjamin Gallinet

We review the research done in recent years in our group on the effects of nanostructure symmetry, and outline its relevance both for nanostructure physics and for computations of their electronic and optical properties. The exemples of C3v and C2v quantum ...

Integrated Hall Microsystem with Current Re-Use

Radivoje Popovic, Pavel Kejik, Predrag Drljaca

A new architecture of a Hall microsystem for low-power applications is presented. The innovation in this paper lies in the re-use of the electric current for biasing of several parts in the microsystem permitting substantial reduction of the current consum ...

Amorphous hafnium silicates: structural, electronic and dielectric properties

Alfredo Pasquarello, Peter Broqvist

Models of amorphous (HfO2)x(SiO2)(1), for varying hafnium, content x are generated by ab initio molecular dynamics. The structural properties are analyzed in terms of pair distribution functions from which typical bond lengths and coordination numbers are ...

Polarization effects in the channel of an organic field-effect transistor

Libero Zuppiroli, Marie-Noëlle Bussac, Jean-David Picon, Hocine Houili

We present the results of our calculation of the effects of dynamical coupling of a charge carrier to the electronic polarization and the field-induced lattice displacements at the gate interface of an organic field-effect transistor (OFET). We find that t ...

Mixed Wannier-Bloch functions for electrons and phonons in periodic systems

Alfredo Pasquarello

We introduce mixed Wannier-Bloch functions for studying electronic and vibrational spectra of periodic systems. These functions carry both spatial localization and limited spectral broadening, thereby combining the advantages of descriptions based on energ ...

Atomic-scale modelling of the Si(100)-SiO2 interface

Alfredo Pasquarello, Angelo Bongiorno

We discuss the structural, electronic and dielectric properties of a model structure of the Si(100)-SiO2 interface that accounts for the amorphous nature of the oxide. After showing that the structural properties of this model are consistent with a variety ...
