Scandium diboride: a semi-metallic, lattice, thermally matched substrate for vertical AlGaN power electronics
MVS Chandrashekhar, Daniel Joel Harrison, Ahamed Raihan +22
We report the properties of hexagonal (space group P6/mmm) scandium diboride () single crystals grown by a laser diode floating zone method at growth rates of ~1mm/…
Enhanced thermal conductivity of (010) (AlxGa1-x)2O3 epitaxial films utilizing indium-catalyzed molecular beam epitaxy
Shivashree Gowda, Stephen Schaefer, Ethan A. Scott +3
(AlxGa1-x)2O3/beta-Ga2O3 transistors are an emerging candidate for high-power and high-frequency electronic devices. beta-Ga2O3 in particular is notably limited for anisotropic low…
Synthesis and Characterization of Compositionally Complex (Gd/Ho/Er/Dy)2Zr2O7 Thin Film Combinatorial Library
Dalton A. Pearl, Jade Holliman, Reece Emory +13
High-throughput synthesis and characterization of novel ceramic materials with improved thermomechanical properties and phase stability are needed to accelerate the discovery of ne…
Lock-In Infrared Thermography: Phase Analysis for Rapid, Wide-Range Thermal Conductivity Measurements
Ethan A. Scott, Jeffrey L. Braun, Jessica Reyes +5
We report on a phase-based lock-in thermography approach, combined with a multilayered thermal model (often employed in thermoreflectance analysis), to measure the thermal conducti…
Crystal growth and characterization of the ultra-high temperature substrate
Evan N. Crites, Sharad Mahatara, Joshua R. Hummel +12
Incorporation of (AGN) semiconductors into high power electronics offers efficiency improvements in power transmission, generation, and use, if approache…
Closing the ultrahigh temperature metrology gap: non-contact thermal conductivity () and spectral emittance () of molybdenum up to 3200 K
Hunter B. Schonfeld, Elizabeth Golightly, Milena Milich +7
Advances in next-generation hypersonic hot structures, high heat-flux fusion or fission components, and laser based additive manufacturing depend on reliable solid state thermal co…
