Enhanced Conversion Efficiencies of Cu2ZnSnS4-Based Thin Film Solar Cells by Using Preferential Etching Technique
Cu2ZnSnS4 (CZTS) thin film solar cells have been fabricated by co-sputtering technique using three targets of Cu, SnS, and ZnS. CZTS-based thin film solar cells over 6.7% efficiency were obtained for
Effect of Amount of Chunky Graphite on Mechanical Properties of Spheroidal-Graphite Cast Iron
Chunky graphite is generated in heavy-section castings, and it is detrimental to the mechanical properties, especially the ductility and toughness, of cast iron. However, there have been few
Rotational Honeycomb Epitaxy of Ru Thin Films on Sapphire (0001) Substrate : Surfaces, Interfaces, and Films
Rotational honeycomb epitaxy of hexagonal Ru films was achieved on c-plane sapphire substrates by pulsed laser ablation with the a-axis ratio of √3. The crystal structure and crystallinity of the Ru
Composition Dependence in BiFeO3 Film Capacitor with Suppressed Leakage Current by Nd and Mn Cosubstitution and Their Ferroelectric Properties
(Nd,Mn)-cosubstituted BiFeO3 (BFO) films with various Nd and Mn compositions were fabricated on a Pt/SrTiO3(100) substrate by pulsed laser deposition. X-ray diffraction patterns and atomic force
