Multisource geophysical investigation of the Acıgöl caldera structure (central Turkey): preliminary results

Neogene and Quaternary volcanic activity formed the large volume ignimbritic units (about 10 different units, namely Cappadocian ignimbritic field) around Nevşehir, Derinkuyu and Acıgöl districts. These large volume ignimbrites are mostly caldera-related products but the calderas are partially or totally buried by later pyroclastic and sedimentary cover. Source estimations for the caldera-related

Nanoelectronic Devices Based on Low-Dimensional Semiconductor Structures

The present thesis reports on results from the fabrication technology development and the corresponding electrical transport measurements of low-dimensional semiconductor structures. The focus of the work has been directed towards two parts: the ballistic transport in nanostructure devices at room temperature, and the development of a charge-sensing technique for quantum dots (QD) in nanowires. B

Abstract in French Selon une hypothèse controversée, le nombre inférieur de femmes par rapport à celui des hommes qui décident de poursuivre des études en sciences, en technologie,en génie et en mathématiques (STGM) serait imputable à un écart entre les sexes dans l’aptitude cognitive (QI). Dans cet article, nous offrons des preuves que cet écart est plutôt lié aux différences dans les styles cogn

High-performance 15 nm diameter InAs nanowire Ω-gate MOSFETs

In this paper we present 15 nm InAs nanowire lateral MOSFETs with an Ω-gate. The nanowires are grown from size-selected Au-aerosols by means of metal-organic vapor phase epixtaxy (MOVPE). In order to reduce the source and drain resistances, n-type dopants were introduced in the bottom and top parts of the nanowire forming a n-i-n structure. We report experimental data for 15 nm InAs nanowire MOSFE
