The invention and development of memory devices are important tasks for facilitating continued innovation in the field of information technology. The authors achieve repeatable switching between a high-resistivity charge-crystalline (or charge-ordered) state and a low-resistivity quenched charge glass via both optical and electrical heating in an organic conductor, -(BEDT-TTF). They observe switching that is one order of magnitude faster in another isostructural organic conductor that requires faster cooling ( K/s) to kinetically avoid charge crystallization, indicating that the material’s critical cooling rate can be a useful guideline for pursuing a faster “correlated-electron phase-change memory (PCM)”. These results establish a clear case whereby practically stable glassy electronic states hidden behind long-range ordered states can be uncovered by adopting hitherto-untried quenching rates and thus underlies a new class of non-volatile PCM.

In the context of plasmonic nanolasers, it has been previously recognized that systems with physically extended modes (as opposed to isolated cavity modes) can support lasing, and plasmonic crystals are a platform for such effects. In the present paper the authors present a general study that explores, from a unified perspective, the lasing properties of plasmonic crystals incorporating optically pumped four-level gain media.
