Experimental Observation of Localized Interfacial Phonon Modes
Zhe Cheng, Ruiyang Li, Xingxu Yan +12
Interfaces impede heat flow in micro/nanostructured systems. Conventional theories for interfacial thermal transport were derived based on bulk phonon properties of the materials m…
Capturing 3D atomic defects and phonon localization at the 2D heterostructure interface
Xuezeng Tian, Xingxu Yan, Georgios Varnavides +9
The 3D local atomic structures and crystal defects at the interfaces of heterostructures control their electronic, magnetic, optical, catalytic and topological quantum properties,…
Imaging real-time amorphization of hybrid perovskite solar cells under electrical biasing
Min-cheol Kim, Namyoung Ahn, Diyi Cheng +11
Perovskite solar cells have drawn much attention in recent years, owing to its world-record setting photovoltaic performances. Despite its promising use in tandem applications and…
Combinatorial search of superconductivity in Fe-B composition spreads
Kui Jin, Richard Suchoski, Sean Fackler +4
We have fabricated Fe-B thin film composition spreads in search of possible superconducting phases following a theoretical prediction by Kolmogorov et al.^1 Co-sputtering was used…
Experimental Evidence of Ferroelectric Negative Capacitance in Nanoscale Heterostructures
Asif Islam Khan, Debanjan Bhowmik, Pu Yu +4
We report a proof-of-concept demonstration of negative capacitance effect in a nanoscale ferroelectric-dielectric heterostructure. In a bilayer of ferroelectric, Pb(Zr0.2Ti0.8)O3 a…
Structural and transport properties of epitaxial NaxCoO2 thin films
A. Venimadhav, A. Soukiassian, D. A. Tenne +9
We have studied structural and transport properties of epitaxial NaxCoO2 thin films on (0001) sapphire substrate prepared by topotaxially converting an epitaxial Co3O4 film to NaxC…
Synthesis and Properties of c-axis Oriented Epitaxial MgB2 Thin Films
S. D. Bu, D. M. Kim, J. H. Choi +10
We report the growth and properties of epitaxial MgB2 thin films on (0001) Al2O3 substrates. The MgB2 thin films were prepared by depositing boron films via RF magnetron sputtering…
In situ epitaxial MgB2 thin films for superconducting electronics
X. H. Zeng, A. V. Pogrebnyakov, A. Kotcharov +11
A thin film technology compatible with multilayer device fabrication is critical for exploring the potential of the 39-K superconductor magnesium diboride for superconducting elect…
Superconducting properties of nanocrystalline MgB thin films made by an in situ annealing process
X. H. Zeng, A. Sukiasyan, X. X. Xi +11
We have studied the structural and superconducting properties of MgB thin films made by pulsed laser deposition followed by in situ annealing. The cross-sectional transmission…
