Effect of Strontium Incorporation on the p -Type Conductivity of Cu2O Thin Films Deposited by Metal-Organic Chemical Vapor Deposition
Article
  • Jul 2016
Temperature-dependent Hall effect and resistivity measurements are performed on polycrystalline Cu2O:Sr thin films deposited on glass substrate by metal organic-chemical vapor deposition. Their electrical properties are studied as a function of the strontium content, as determined by wavelength dispersive X-ray spectrometry. These electrical transp...

We present a synthetic approach to the kinds of housing found in the mountainous Alta Rocca sector of southern Corsica during the late Bronze Age and Early Iron Age. Study of protohistoric non-fortified sites in Corsica is relatively new, but the numerous projects carried out in recent years reveal the structural and developmental complexity of liv...
Growth and characterization of Sr-doped Cu2O thin films deposited by metalorganic chemical vapor deposition
Article
  • Feb 2015
Strontium-doped Cu2O thin films were successfully grown through metalorganic chemical vapor deposition method. The films were characterized regarding their morphology, composition, electrical, and optical properties. The composition of the films, and especially their strontium concentration, is the dominant factor which mainly affects the morpholog...
Study of the growth of p-type transparent conducting oxides thin films for transparent electronic or photovoltaic applications
Article
  • Jan 2015
Transparent electronic is currently limited by the lack of a really performant p-type transparent conducting oxide (TCO), which makes the elaboration of a transparent p-n junction challenging. Cuprous oxide Cu2O is a promising p-type TCO, but its optical transmittance in the visible spectrum is limited by its relatively low band gap (2.1 eV). In th...

... Namely, the film deposited at 13 mTorr has the highest crystal quality with the lowest resistivity value of 10.2 Ωcm, corresponding to a charge carrier concentration and a mobility value of 1.72 × 10 17 cm − 3 and 3.13 cm 2 V − 1 s − 1 , respectively. We also note that the resistivity of the Mg: Cu 2 O thin film achieved at an Ar pressure of 13 mTorr matches with the electrical properties of Sr-doped Cu 2 O thin films [50]. ...

... The site of Cuciurpula was selected because of its acidic sediment, which is unfavourable to micro-organism activity (DeLaune et al. 1981;Moucawi et al. 1981;Drieu et al. 2018). Twelve potsherds were sampled from this open-air site dating from the end of the Bronze Age to the first half of the Iron Age and situated in the mountainous region of central south Corsica (Serra-di-Scopamena and Sorbollano, France;Peche-Quilichini et al. 2015). In-depth analysis of the ceramic fabric has not yet been carried out, but most of the pottery seems to be made of local granitic earth with a high quantity of non-plastic inclusions of variable grain size (Peche-Quilichini 2010). ...

... Other authors find that an increase in Sr content decreases resistivity from 10 6 to 10 2 Ωcm for film with 5-6% of Sr. Unlike Nolan's calculation [90], no increase of the band gap was recorded in the experiments while morphology is affected by Sr content indeed [131]. ...
