Phase Transitions in Low-Dimensional Layered Double Perovskites: The Role of the Organic Moieties
Beatriz Martín-García, Davide Spirito, Giulia Biffi +3
Halide double perovskites are an interesting alternative to Pb-containing counterparts as active materials in optoelectronic devices. Low-dimensional double perovskites are fabrica…
Tailoring Photoluminescence by Strain-Engineering in Layered Perovskite Flakes
Davide Spirito, María Barra-Burillo, Francesco Calavalle +6
Strain is an effective strategy to modulate the optoelectronic properties of 2D materials, but it has been almost unexplored in layered hybrid organic-inorganic metal halide perovs…
Magnetic properties of layered hybrid organic-inorganic metal-halide perovskites: transition metal, organic cation and perovskite phase effects
Yaiza Asensio, Sergio Marras, Davide Spirito +6
Understanding the structural and magnetic properties in layered hybrid organic-inorganic metal halide perovskites (HOIPs) is key for their design and integration in spin-electronic…
Local Alloy Order in a Ge1-xSnx/Ge Epitaxial Layer
Agnieszka Anna Corley-Wiciak, Shunda Chen, Omar Concepción +6
The local ordering of atoms in alloys directly has a strong impact on their electronic and optical properties. This is particularly relevant in nonrandom alloys, especially if they…
