Nowadays, chalcogenide-based phase change materials (PCMs) are proving themselves superior in the category of memory devices due to a combination their unique set properties.

Electrical switching in germanium telluride glasses containing metallic atoms (Cu and Ag) has been investigated. All these glasses are found to exhibit memory switching. The switching fields of these glasses are compared with the thermal parameters evaluated from DSC studies and the results are explained on the basis of the thermal model. The composition dependence of the switching field and th...

Pb2Bi2Te5: a layered chalcogenide with thermoelectric figure of merit strongly affected by the change in stacking sequence.

We report on the generation of two-octave mid-infrared supercontinuum in stock, unprocessed, large core chalcogenide fiber pumped by a fiber-based laser delivering 35 kW, 180 fs pulses at 4.53 μm.

Multimaterial optical fibers combining tellurite with chalcogenide glasses and featuring thin polymer structures are fabricated via the thermal drawing process. It is demonstrated that micrometric polyethersulfone films can be embedded within larger elongated tellurite/chalcogenide glass architectures. Taking advantage of strong chemical reactivity contrasts which exist in considered fiber geom...

We demonstrate experimentally that the distribution of decay rates nitrogen-vacancy centers in diamond becomes narrower by over five times for nanodiamonds embedded thin chalcogenide films.

This Report is a collation of the information supplied to EOARD 2014-2017 comprising the original Proposal, intermediate Reports consisting of PowerPoint slides (Feb. 2015) and interim Progress Report (June 2015) and the Final Report. The EOARD funding award ($50k) was used in its entirety to purchase a bespoke midinfrared quantum cascade laser (MIR-QCL) for use in far-field and near-field asse...
