Nondestructive Evaluation of Engine Run Turbine Blades Using Laser Ablation and Photoluminesence Stress Measurements
<p>Thermal barrier coating (TBC) systems are an integral part of today’s engine parts. The ceramic coatings offer protection from thermal loads imposed on components such as turbine blades. Coated engine parts are currently taken out of operation based on group data when statistical minimums are …

Monte Carlo studies of ground-state & optical properties of multiexcitonic complexes in semiconductors
… interactions, play an important role in the photoluminesence of direct- and indirect-gap semiconductors and semiconductor impurities. We calculate the ground-state and optical properties of several multiexciton systems within the spherical effective mass approximation, focusing on the role of …

Characterization and device applications of II-VI nanocomposites
… films characterized with x-ray diffraction and photoluminesence measurements. QD film / ZnS film structures are also considered, with atomic layer deposition used as the method for depositing the ZnS to improve the film uniformity as well as to maintain high quality deposition at temperatures …

Manufacturability of gallium arsenide/aluminum gallium arsenide lasers grown by molecular beam epitaxy
… lower threshold density, higher quantum well photoluminesence intensity, and secondary ion mass spectroscopy data. The high growth temperatures required to prevent oxygen incorporation in the quantum well result in additional technical obstacles stymieing full exploitation of the growth …
