Tuning the properties of high-Tc superconductor & Sr2IrO4, and exploring transport through single nanocrystals
… the AC magnetic susceptibility study of high-temperature superconductor YBa$_2$Cu$_3$O$_{7-\delta}$, the ionic-liquid gating study of the Mott insulator Sr$_2$IrO$_4$, and the single-electron study of quantum dot device with self-assembled nanocrystal PbS. Chapter 1 covers a general …

Dynamic Resistance of High-Tc Superconductor and Its Application in Flux Pumped Superconducting Magnets
High temperature superconductors are ideal materials for use in extra high magnetic fields owing to their capability of transporting high-density DC current with little power loss. Hence, superconducting magnets are already widely used in areas such as magnetic resonance imaging (MRI), particle …

Chemical Vapor Deposition of Metal Diboride and Metal Oxide Thin Films From Borohydride-Bonded Precursors
The high Tc superconductor MgB2 were deposited at low temperatures (T = 300°C--400°C) from a recently developed highly volatile borohydride-bonded Mg precursor, by means of catalyst-enhanced chemical vapor deposition. The films are stoichiometric and highly crystallized, however, the …

Variable Temperature Scanning Tunneling Microscopy Study of a High Temperature Superconductor Bi2Sr2CaCu2O8+d
… the electronic states of a slightly underdoped high-TC superconductor Bi2Sr2CaCu2O8+d as a function of temperature. We have demonstrated for the first time that atomicallyresolved spectroscopic studies at elevated temperatures are possible. We have used this new experimental capability to map …

Hall effect in untwinned single-crystal superconducting YBa2Cu307-y
… in untwinned single-crystal YBa2Cu3o7_Y, a high-Tc superconductor. The crystals were grown using a technique that we invented, in which untwinned domains are produced naturally without applying stress to the sample. The Hall effect measurements were directed at understanding fluctuation …

Spin liquids, exotic phases and phase transitions
… state of matter firstly motivated from study on High-Tc superconductor. The most striking property of spin liquids is that they do not break any physical symmetry, yet there are many types of them, meaning a phase transition is necessary from one spin liquid to another. It was a long debate about …

Magnetic properties of graphite and Bi2Sr2CaCu2O8+δ
… circulating currents around artificial holes in highly oriented graphite was studied by highly sensitive magnetization measurements. The obtained results provide hints for the possible existence of superconducting regions inside the bulk highly ordered graphite. In the present thesis, a further …

Analysis of a space experimental design for high-Tc superconductive thermal bridges
… are limited due to cryogenic evaporation. High-temperature superconductor (HTS) materials have been proposed by researchers at the National Aeronautics and Space Administration Langley's Research Center (NASA-LaRC) as an alternative to the currently used manganin wires for electrical …
