The global demand for data storage and processing is increasing exponentially. To deal
with this challenge, massive efforts have been devoted to the development of advanced …

Chalcogenide phase-change materials (PCMs), such as Ge-Sb-Te alloys, have shown
outstanding properties, which has led to their successful use for a long time in optical …

Amorphous solids, or glasses, are distinguished from crystalline solids by their lack of long-
range structural order. At the level of two-body structural correlations, glassformers show no …

We review several methods for the calculation of vibrational spectra from ab initio molecular
dynamics (AIMD) simulations and we present a new implementation in the trajectory …

Phase‐change materials can rapidly and reversibly be switched between an amorphous
and a crystalline phase. Since both phases are characterized by very different optical and …

GeTe is a prototypical phase change material of high interest for applications in optical and
electronic nonvolatile memories. We present an interatomic potential for the bulk phases of …

The 3D integration technology in semiconductor fabrication requires a key component, the
ovonic threshold switching (OTS) selector, to suppress the current leakage. The As doped …

Phase change materials are of great interest as active layers in rewritable optical disks and
novel electronic nonvolatile memories. These applications rest on a fast and reversible …

Despite its simple chemical constitution and unparalleled technological importance, the
phase‐change material germanium telluride (GeTe) still poses fundamental questions. In …
