The properties (electric, optic, and magnetic) of impurities and dopants in semiconductors are strongly dependent on the lattice sites which they occupy. Although the main occupied site, for a given impurity-host combination, can often be predicted based on chemical similarities between impurity and host elements, such expectations fail in many cases. Furthermore, minority sites (in case of...

We look on interaction between molecules and light at the nanoscale, by fabrication of metallic nanostructures (plasmonic systems). The interaction (coupling) is interesting both in the effect the molecules have on the plasmons and in the effect the plasmons have on the molecular transitions. Thus, molecules which are immeressed is the plasmonic field, may undergo photochemical processes...

Amorphous and transparent semiconductor oxides are key components of new thin film transistors (TFTs), solar cells electrodes and displays. By controlling their stoichiometry, they can be used as TFT channel (semiconductive behavior) or as transparent electrode (conductive behavior). Recently, room temperature deposited indium zinc oxide (IZO) and indium gallium zinc oxide (IGZO) thin films...

Photosynthesis has found an ultrafast and highly efficient way of converting the energy of the sun into electrochemical energy. The solar energy is collected by Light-Harvesting complexes (LHC) and then transferred to the Reaction Center (RC) where the excitation energy is converted into a charge separated state with almost 100% efficiency. That separation of charges creates an electrochemical...

Artificial photosynthesis is envisioned by many to be an important component of mankind’s long-term energy solution. Bio-inspired photosystems appear most promising, but the first constructs over the past few years have clearly pointed to the infancy of this field [1]. To make progress, a very detailed understanding of natural photosynthesis is required in order to wisely extract the most...

We have shown that electron transport (ETp), i.e., conduction, through protein monolay-ers in a solid state–like configuration is remarkably efficient, compared to most molecules, including conjugated ones.1 Some proteins also have a natural electron transfer (ET) function and ET and ETp are related, but while nature regulates ET via redox chemistry, where control over the process is achieved...

Although the self-assembled InAs/GaAs quantum dots (QDs) are intensively studied during more than the last twenty years, the mass production of QD lasers started only in 2010 and the production of telecommunication QD lasers was announced even last year [1]. The main problem is the complexity of QD preparation process which includes not only the epitaxial layer growth but also...

ZnO is a wide band gap semiconductor having excellent properties for fabricating optoelectronic devices operating at the wavelength of ultra-violet (UV). The realization of fabricating UV optoelectronic devices with ZnO based technology is hindered by the asymmetric p-type doping difficulty, which is related to the poor understanding of the defects, defect compensation, and defect control in...

Introduction
One-dimensional group-III Nitride nanorods (NR), have drawn a large interest during the past decade thanks to great prospects for improved optoelectronics by e.g., increased quantum efficiency, higher sensitivity, lower heat generation, etc. as compared to bulk and quantum well-based devices.
Magnetron Sputter Epitaxy (MSE) allows for epitaxial growth of Al1-xInxN NRs as well...
