ABSTRACT Phase-change memory (PCM), recently developed as the storage-class
memory in a computer system, is a new non-volatile memory technology. In addition, the …

The ability to resolve the dynamics of matter on its native temporal and spatial scales
constitutes a key challenge and convergent theme across chemistry, biology, and materials …

The nonequilibrium ultrafast carrier dynamics of the photoinduced phase transition in
chalcogenide phase-change material (rocksalt Ge-Sb-Te) has been investigated via real …

Ultrafast photoexcitation can decouple the multilevel nonequilibrium dynamics of electron–
lattice interactions, providing an ideal probe for dissecting photoinduced phase transition in …

As a phase change material (PCM), antimony exhibits a set of desirable properties that
make it an interesting candidate for photonic memory applications. These include a large …

In addition to long‐range periodicity, local disorder, with local structures deviating from the
average lattice structure, dominates the physical properties of phonons, electrons, and spin …

The microscopic arrangement of atoms and molecules is the determining factor in how
materials behave and perform; ie, the structure determines the property, a traditional …

Rhenium disulfide with a distorted crystal structure has recently attracted tremendous
attention for its excitonic and highly anisotropic properties. While ultrafast spectroscopies …

Threshold switching (TS) materials, such as amorphous chalcogenide, have received
significant attention for their application in storage class memory and in-memory computing …

We investigate the ultrafast response of crystalline Ge 2 Sb 2 Te 5 nanoparticles (NPs)
below the phase transformation threshold fluence. The observed rapid change of the optical …
