Lattice vibrations and dynamic disorder in two-dimensional hybrid lead-halide perovskites
Vlad Alexandru Dragomir, Stefanie Neutzner, Claudio Quarti +7
By means of non-resonant Raman spectroscopy and density functional theory calculations, we measure and assign the vibrational spectrum of two distinct two-dimensional lead-iodide p…

Point defects in models of amorphous silicon and their role in structural relaxation
Cristiano L. Dias, Laurent J. Lewis, S. Roorda
We have used tight-binding molecular-dynamics simulations to investigate the role of point defects (vacancies and interstitials) on structural relaxation in amorphous silicon. Our…
