A method for the direct correlation at the nanoscale of structural and optical properties of single GaAs nanowires is reported. Nanowires consisting of 100% wurtzite and nanowires presenting zinc-blende/wurtzite polytypism are investigated by photoluminesc ...
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 ...
Two molecules containing two phenylphosphaalkene moieties linked by an anthracene (1) or by a naphthalene (2) ring have been synthesized and their crystal structures have been determined. While electrochemical measurements show that these two systems are e ...
The effect of dimensionality on materials properties has become strikingly evident with the recent discovery of graphene. Charge ordering phenomena can be induced in one dimension by periodic distortions of a material's crystal structure, termed Peierls or ...
We report on the synthesis, the layered triclinic P (1) over bar crystal structure, band structure and Fermi surface analysis and preliminary transport and ESR data of beta-(EDT-TTF-I-2)(2)((1+x)center dot+)HO2C-CH=CH-CO2--O2C-CH=CH-CO2-, a m ...
The topic of this dissertation is embedded into the new-born field of inorganic nanowires. The research was focused on zinc oxide (ZnO) nanowires, in particular, which besides posing fundamental questions in physics, promise broad range of applications. Zn ...
The electrical conductivities of complex hydrides Li2(BH 4)(NH2) and Li4(BH4)(NH 2)3 consisting of (BH4)- and (NH2)- anions are investigated focusing on their low melting temperatures (365 K for Li2(BH4)(NH2) and 490K for Li4(BH4)(NH2)3). The two hydrides ...
We present a gate-dependent Raman spectroscopy and electric transport measurements of an individually connected multiwall carbon nanotube in the field-effect transistor configuration at room temperature. We discuss the origin of the four distinct sharp mod ...
The crystal structure of the neuropeptide proctolin (Arg-Tyr-Leu-Pro-Thr) is reported revealing the solid-state conformation of its molecules and their association in the crystal. ...
Hematite is a semiconducting mineral with a role in natural photoelectrochemical processes, and has been studied from the viewpoint of solar energy utilization. Hematite is an anisotropic conductor, with faster conduction parallel to (001) planes. Flatband ...
