ARXPS-studies ofcˆ-axis textured YBa2Cu3Ox-films [PDF]

, 1988
YBa2Cu3Ox sputter deposited cold on MgO grows in O2 annealing epitaxially to a transparent, superconducting film with Tc 80K. The unscraped surfaces of these films are smooth showing XPS lines changing with photoelectron take-off angle.

Nematic fluctuations in the cuprate superconductor Bi2Sr2CaCu2O8+δ [PDF]

Nature Communications, 2019
Establishing the presence and the nature of a quantum critical point in their phase diagram is a central enigma of the high-temperature superconducting cuprates.

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range

Advanced Electronic Materials, EarlyView.
A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Pseudogap and its connection to particle-hole asymmetry electronic state and Fermi arcs in cuprate superconductors

, 2012
The particle-hole asymmetry electronic state of cuprate superconductors and the related doping and temperature dependence of the Fermi arc length are studied based on the kinetic energy driven superconducting mechanism.

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.

Universal linear-temperature resistivity: possible quantum diffusion transport in strongly correlated superconductors

Scientific Reports, 2017
The strongly correlated electron fluids in high temperature cuprate superconductors demonstrate an anomalous linear temperature (T) dependent resistivity behavior, which persists to a wide temperature range without exhibiting saturation. As cooling down,

Dynamical charge and spin density wave scattering in cuprate superconductor

, 2010
We show that a variety of spectral features in high-T_c cuprates can be understood from the coupling of charge carriers to some kind of dynamical order which we exemplify in terms of fluctuating charge and spin density waves.

1,1‐Disubstituted Vinylbromides: Versatile Building Blocks for the Synthesis of Nitrogen‐Containing Heterocycles

European Journal of Organic Chemistry, EarlyView.
1,1‐Disubstituted vinylbromides are key intermediates for constructing nitrogen‐containing heterocycles. This review provides an overview of the synthetic applications of 1,1‐disubstituted vinylbromides and summarizes recent developments in reaction methodologies, mechanistic insights, and the structural diversity of N‐heterocyclic compounds accessible
