Role of Ge and Si substrates in higher-k tetragonal phase formation and interfacial properties in cyclical atomic layer deposition-anneal Hf1-xZrxO2/Al2O3 thin film stacks
(Journal of Applied Physics, 2016)Using a five-step atomic layer deposition (ALD)-anneal (DADA) process, with 20 ALD cycles of metalorganic precursors followed by 40 s of rapid thermal annealing at 1073 K, we have developed highly crystalline Hf1-xZrxO2 ... -
Safety and efficacy of megakaryocytes induced from hematopoietic stem cells in murine and nonhuman primate models
(Stem Cells Translational Medicine, 2016)Because of a lack of platelet supply and a U.S. Food and Drug Administration-approved platelet growth factor, megakaryocytes have emerged as an effective substitute for alleviating thrombocytopenia. Here, we report the ... -
Scalable fabrication of coupled NV center - photonic crystal cavity systems by self-aligned N ion implantation
(2017, 2017)Towards building large-scale integrated photonic systems for quantum information processing, spatial and spectral alignment of single quantum systems to photonic nanocavities is required. Here, we demonstrate spatially ... -
