Spontaneous formation of nanostructures during pulsed laser deposition of epitaxial half-Heusler TiNiSn on MgO(001)

APL Materials, 2019
The half-Heusler alloy TiNiSn is a promising material for thermoelectric applications that is inexpensive and non-toxic. We demonstrate the epitaxial growth of smooth TiNiSn thin films on MgO(001) single crystal substrates by pulsed ...

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, EarlyView.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Ion beam induced modification of exchange interaction and spin-orbit coupling in the Co$_2$FeSi Heusler compound

, 2007
A Co$_2$FeSi (CFS) film with L2$_1$ structure was irradiated with different fluences of 30 keV Ga$^+$ ions. Structural modifications were subsequently studied using the longitudinal (LMOKE) and quadratic (QMOKE) magneto-optical Kerr effect.

High Power Density for All‐Fe2VAl‐based Thermoelectric Module by Enhancing the Power Factor of p‐type Leg Through Defect‐Engineering and Wetting Effect

Small Methods, EarlyView.
ABSTRACT The high thermoelectric performance of Fe2VAl stems from its sharply rising band edges on either side of the band gap, which is highly sensitive to composition. Addressing reproducibility and scale‐up challenges, we have developed a strategy to enhance its p‐type thermoelectric performance by defects and grain boundary engineering through ...
