Epitaxial Er-doped Y2O3 on silicon for quantum coherent devices
APL Materials, 2020 Rare-earth ions (REIs) have incomplete 4f shells and possess narrow optical intra-4f transitions due to shielding from electrons in the 5s and 5p orbitals, making them good candidates for solid-state optical quantum memory.

Advanced Materials, EarlyView.The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

High-temperature phase relations of ZrN–ZrO2–Y2O3 ternary system
Journal of Advanced Ceramics, 2018 Zirconium nitride (ZrN) ceramics were prepared via hot pressed sintering (HP) at 1750 °C in N2 atmosphere with ZrO2–Y2O3 as sintering additive. X-ray diffraction was applied to analyze the phase composition of the as-prepared ceramics to study the high ...
