Metal–insulator transition (MIT) coupled with an ultrafast, significant, and reversible resistive
change in Mott insulators has attracted tremendous interest for investigation into next …

First-principles methods can provide insight into materials that is otherwise impossible to
acquire. Density functional theory (DFT) has been the first-principles method of choice for …

The known crystal structures of solids often correspond to the most thermodynamically
stable arrangement of atoms. Yet, oftentimes there exist a richly diverse set of alternative …

The crossbar array-based resistive memory is considered a potential architecture for high-
density nonvolatile memory applications. However, the sneak current path problem …

Vanadium dioxide is one of the most studied strongly correlated materials. Nonetheless, the
intertwining between electronic correlation and lattice effects has precluded a …

Processing, storing, and transmitting information accounts for∼ 10% of global energy use;
projections suggest that computational energy demands will be 10× higher than the …

Since the early 2000s, the impending end of Moore's scaling, as the physical limits to
shrinking transistors have been approached, has fueled interest in improving the …

We present a combined density-functional theory and single-site dynamical mean-field
theory (DMFT) study of vanadium dioxide (VO 2) using an unconventional set of bond …

The structural phase transition (SPT) and metal–insulator phase transition (MIT) always
occur simultaneously upon heating from the low-temperature insulator M1 phase to the high …

In this study, we report the Poole-Frenkel induced threshold switching characteristics of
niobium dioxide (NbO 2) films by tuning oxygen stoichiometry. Similar to correlated oxides …
