Grain Boundaries Limit the Charge Carrier Transport in Pulsed Laser Deposited α-SnWO<sub>4</sub> Thin Film Photoabsorbers Open
Recently, α-SnWO4 attracted attention as a material to be used as a top absorber in a tandem device for photoelectrochemical water splitting due to its nearly optimum band gap of ∼1.9 eV and an early photocurrent onset potential of ∼0 V ve…
Observation of sagittal X-ray diffraction by surface acoustic waves in Bragg geometry Open
X-ray Bragg diffraction in sagittal geometry on a Y-cut langasite crystal (La 3 Ga 5 SiO 14 ) modulated by Λ = 3 µm Rayleigh surface acoustic waves was studied at the BESSY II synchrotron radiation facility. Owing to the crystal lattice mo…
