Acoustic Phonon Lifetimes Limit Thermal Transport in Methylammonium Lead Iodide
Aryeh Gold-Parker, Peter M. Gehring, Jonathan M. Skelton +6
Hybrid organic-inorganic perovskites (HOIPs) have become an important class of semiconductors for solar cells and other optoelectronic applications. Electron-phonon coupling plays…
