Structural Variations and Ionizing Radiation Hardness of Perovskite Solar Cells with Guanidinium Cation

Adding so-called oversized organic cations to lead-halide perovskites has emerged as a promising route to enhance the stability and efficiency of perovskite solar cells (PSCs). These additives can induce quasi-2D phases, yielding “2D–3D” hybrids. Here, we study methylammonium (MA) lead iodide PSCs incorporating guani...

Independent Tuning of Surface Acoustic-Waves and Spin-Waves via Buffer-Layer Engineering in Co2FeGe Heusler Thin Films

Understanding and controlling acoustic and spin-wave excitations in magnetic thin films is critical for the development of magnonic and spin-acoustic devices. We report on the use of Cr and W buffer layers to independently modify the acoustic and magnetic excitations in Co2FeGe full-Heusler thin films grown on MgO(001)...
