Epitaxial cerium oxide (CeO2) buffer layer has been grown on lanthanum aluminate (LAO) single crystal substrates for fabrication of c-axis oriented YBa2Cu3O72x (YBCO). Precursor solution of cerium acetylacetonates with viscosity of 0.6 centipoises was spin coated on the 1 × 1 cm area LAO substrates. The calcination was carried out by very slow ramp (18C per minute) until the final temperature o...

Abstract: Chuang Tzu (????), as a traditional Chinese canon, has been translated into English for more than 100 years since 1881, successfully carving niche in the realm of world literature, which become an earth-shattering cultural event academia overseas sinology and literature. According to statistics, book 12 full translations, 50 selected two adaptations. The metamorphosis process “full tr...

OBJECTIVE To provide an overview of the household dietary diversity score and the food consumption score, two indicators used for food security assessment and surveillance, and compare their performance in food security assessments in three countries. DESIGN Cross-sectional cluster sampling design using an interview-administered structured questionnaire on household food security, including h...

Emergent phases in the two-dimensional electron gas (2DEG) formed at the interface between two insulating oxides have attracted great attention in the past decade. We present ab-initio electronic structure calculations for the interface between a Mott insulator GdTiO3 (GTO) and a band insulator SrTiO3 (STO) and compare our results with those for the widely studied LaAlO3/SrTiO3 (LAO/STO) interf...

We have experimentally explored a new approach to local anodic oxidation (LAO) of a semiconductor heterostructures by means of atomic force microscopy (AFM). We have applied LAO to an InGaP/AlGaAs/GaAs heterostructure. Although LAO is usually applied to oxidize GaAs/AlGaAs/GaAs-based heterostructures, the use of the InGaP/AlGaAs/GaAs system is more advantageous. The difference lies in the use o...
