Thermoelectric Performance of Tetrahedrite (CuSbS) Thin Films: The Influence of the Substrate and Interlayer.

In the present work, tetrahedrite CuSbS thin films were deposited on various substrates via aerosol-assisted chemical vapor deposition (AACVD) using diethyldithiocarbamate complexes as precursors. A buffer layer of SbO with a small lattice mismatch to CuSbS was applied to one of the glass substrates to improve the quality of the deposited thin film. The buffer layer increased the coverage of the CuSbS thin film, resulting in improved electrical transport properties.

Exceptional Thermoelectric Performance of Cu(Zn,Fe,Cd)SnS Thin Films.

High-quality Cu(Zn,Fe,Cd)SnS (CZFCTS) thin films based on the parent CZTS were prepared by aerosol-assisted chemical vapor deposition (AACVD). Substitution of Zn by Fe and Cd significantly improved the electrical transport properties, and monophasic CZFCTS thin films exhibited a maximum power factor (PF) of ∼0.22 μW cm K at 575 K.

Family screening for bicuspid aortic valve and aortic dilatation: a meta-analysis.

Aims: International guidelines recommend screening of first-degree relatives (FDR) of people with bicuspid aortic valves (BAVs). However, the prevalence of BAV and of aortic dilatation amongst family members is uncertain.

Methods And Results: A systematic review and meta-analysis of original reports of screening for BAV.

Enhanced Thermoelectric Performance of Tin(II) Sulfide Thin Films Prepared by Aerosol Assisted Chemical Vapor Deposition.

Orthorhombic SnS exhibits excellent thermoelectric performance as a consequence its relatively high Seebeck coefficient and low thermal conductivity. In the present work, polycrystalline orthorhombic SnS thin films were prepared by aerosol-assisted chemical vapor deposition (AACVD) using the single source precursor dibutyl-(diethyldithiocarbamato)tin(IV) [Sn(CH)(SCN(CH))]. We examined the effects of the processing parameters on the composition, microstructure, and electrical transport properties of the SnS films.
