Crystal Growth and Characterization of Bulk Sb2Te3Topological Insulator

, 2018
The Sb2Te3 crystals are grown using the conventional self flux method via solid state reaction route, by melting constituent elements (Sb and Te) at high temperature (850 C), followed by slow cooling (2 C per hour).The weak anti localization (WAL ...

Controlled long-range interactions between Rydberg atoms and ions [PDF]

, 2016
We theoretically investigate trapped ions interacting with atoms that are coupled to Rydberg states. The strong polarizabilities of the Rydberg levels increases the interaction strength between atoms and ions by many orders of magnitude, as compared to ...

Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

Giant barocaloric effects over a wide temperature range in superionic conductor AgI

Nature Communications, 2017
Barocaloric materials offer promise in solid-state cooling devices, but few materials have been show to display giant barocaloric effects near room temperature.

Distinct Effect of Cooling Rate on Structure and Electrochemical Performance of Lithium Rich Layered Oxides: a Case Study of 0.3Li2MnO3·0.7LiNi0.5Mn0.5O2

International Journal of Electrochemical Science, 2014
0.3Li2MnO3∙0.7LiNi0.5Mn0.5O2 is prepared by a solid-state method with a two-step heating process, and the effect of cooling rate after the first-step heating on structure and electrochemical behavior of the obtained material is studied.

Optical one-way quantum computing with a simulated valence-bond solid

, 2010
One-way quantum computation proceeds by sequentially measuring individual spins (qubits) in an entangled many-spin resource state. It remains a challenge, however, to efficiently produce such resource states.

Purcell-enhanced solid-state laser cooling

We show that Purcell effect can lead to a substantial enhancement in the maximum cooling power for solid-state laser cooling. We numerically demonstrate such enhancement in a patterned slot-waveguide structure using ytterbium-doped silica as the active material.

Investigations of Cooling Efficiencies in Solid-State Electrocaloric Device

Integrated Ferroelectrics, 2012
Electrocaloric working elements are modeled by 2-D geometry and the thermodynamic efficiencies of Carnot, Ericsson and Brayton cycles were investigated in a solid-state electrocaloric cooling device. Using a comprehensive model for coupled thermal, electrical interactions in ferroelectric PMN-0.3PT single crystals, we demonstrated high Carnot ...

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates

Advanced Engineering Materials, EarlyView.
An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,

Polariton Bose-Einstein condensate at room temperature in a Al(Ga)N nanowire-dielectric microcavity with a spatial potential trap

, 2012
A spatial potential trap is formed in a 6.0 {\mu}m Al(Ga)N nanowire by varying the Al composition along its length during epitaxial growth. The polariton emission characteristics of a dielectric microcavity with the single nanowire embedded in-plane has ...
