Mechanically Exfoliated Metallic Delafossite PdCoO2 Nanomembranes: Quantum Transport and Electrical Evaluation Toward Interconnect Applications
Chengyu Zhu, Pahuni Jain, Yi Zhang +6
Metallic delafossite oxides have drawn attention for their ultralow resistivity and coherent electronic transport. However, mesoscopic transport studies are hindered by the limited…
Demonstration of High-Performance Ultra-Wide Bandgap SrSnO Top-Gated MOSFETs
Junghyun Koo, Weideng Sun, Donghwan Kim +6
We report the demonstration of high-performance top-gated metal-oxide-semiconductor field-effect transistors (MOSFETs) based on the ultra-wide bandgap perovskite oxide SrSnO (S…
High-Performance Ultra-Wide-Bandgap CaSnO3 Metal-Oxide-Semiconductor Field-Effect Transistors
Weideng Sun, Junghyun Koo, Donghwan Kim +8
The increasing demand for high-voltage and high-power electronic applications has intensified the search for novel ultrawide bandgap (UWB) semiconductors. Alkaline earth stannates…
A new critical growth parameter and mechanistic model for SiC nanowire synthesis via Si substrate carbonization: the role of H/CH gas flow ratio
Junghyun Koo, Chinkyo Kim
SiC structures, including nanowires and films, can be effectively grown on Si substrates through carbonization. However, growth parameters other than temperature, which influence t…
