Preferred corrosion pathways for oxygen in Al2Ca-twin boundaries and dislocations
Nicolas J. Peter, Daniela Zander, Xumeng Cao +5
With an ongoing discussion on the oxygen diffusion along crystal defects remaining, it is difficult to study this phenomenon in Al containing intermetallic materials due to its rap…
Correlating atom probe tomography with X-Ray and electron spectroscopies to understand microstructure-activity relationships in electrocatalysts
Baptiste Gault, Kevin Schweinar, Siyuan Zhang +4
The search for a new energy paradigm with net-zero carbon emissions requires new technologies for energy generation and storage that are at the crossroad between engineering, chemi…
Dynamic doping and Cottrell atmosphere optimize the thermoelectric performance of n-type PbTe
Yuan Yu, Chongjian Zhou, Xiangzhao Zhang +9
High thermoelectric energy conversion efficiency requires a large figure-of-merit, zT, over a broad temperature range. To achieve this, we optimize the carrier concentrations of n-…
Dopant-segregation to grain boundaries controls electrical conductivity of n-type NbCo(Pt)Sn half-Heusler alloy mediating thermoelectric performance
Ting Luo, Federico Serrano-Sánchez, Hanna Bishara +12
Science-driven design of future thermoelectric materials requires a deep understanding of the fundamental relationships between microstructure and transport properties. Grain bound…
Different Photostability of BiVO4 in Near-pH-Neutral Electrolytes
Siyuan Zhang, Ibbi Ahmet, Se-Ho Kim +11
Photoelectrochemical water splitting is a promising route to produce hydrogen from solar energy. However, corrosion of semiconducting photoelectrodes remains a fundamental challeng…
Could face-centered cubic titanium in cold-rolled commercially-pure titanium only be a Ti-hydride?
Yanhong Chang, Siyuan Zhang, Christian H. Liebscher +7
A face-centered cubic (FCC) phase in electro-polished specimens for transmission electron microscopy of commercially pure titanium has sometimes been reported. Here, a combination…
Reproducible Performance Improvements to Monolayer MoS2 Transistors through Exposed Material Forming Gas Annealing
Nicholas B. Guros, Son T. Le, Siyuan Zhang +4
Metal-mediated exfoliation has been demonstrated as a promising approach for obtaining large-area flakes of 2D materials to fabricate prototypical nanoelectronics. However, several…
Rational Strain Engineering in Delafossite Oxides for Highly Efficient Hydrogen Evolution Catalysis in Acidic Media
Filip Podjaski, Daniel Weber, Siyuan Zhang +9
The rational design of hydrogen evolution reaction (HER) electrocatalysts which are competitive with platinum is an outstanding challenge to make power-to-gas technologies economic…
Quantum Capacitance-Limited MoS2 Biosensors Enable Remote Label-Free Enzyme Measurements
Son T. Le, Nicholas B. Guros, Robert C. Bruce +7
We have demonstrated atomically thin, quantum capacitance-limited, field-effect transistors (FETs) that enable the detection of pH changes with ~75-fold higher sensitivity (4.4 V/p…
Electronic structure and local distortions in epitaxial ScGaN films
S. M. Knoll, M. Rovezzi, S. Zhang +2
High energy-resolution fluorescence-detected X-ray absorption spectroscopy and density functional theory calculations were used to investigate the local bonding and electronic stru…
Tunable optoelectronic and ferroelectric properties in Sc-based III-nitrides
Siyuan Zhang, David Holec, Wai Y. Fu +2
Sc-based III-nitride alloys were studied using Density Functional Theory with special quasi-random structures and were found to retain wide band gaps which stay direct up to x = 0.…
