Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

The excellent interfacial blocking effect in SiCf/Ni3Al composites towards high strength enabled by (Y/Y2O3)n multilayered diffusion barrier coating

Materials & Design
Y2O3 has been regarded as an effective diffusion barrier in SiCf/Ni composites to block the violent interfacial reactions, however, its high intrinsic brittleness makes it susceptible to cracking and/or peeling off during the consolidation process ...

Electric field modulation of thermopower for transparent amorphous oxide thin film transistors

, 2010
To clarify the electronic density of states (DOS) around the conduction band bottom for state of the art transparent amorphous oxide semiconductors (TAOSs), InGaZnO4 and In2MgO4, we fabricated TAOS-based transparent thin film transistors (TTFTs) and ...

Formation of Y2O3 and Y2O3:Eu(III) by Electrodeposition in Organic Electrolyte.

Journal of the Surface Finishing Society of Japan, 1993
Formation of yttrium oxide by electrodeposition was studied in DMF containing YCl3 and a small amount of water, and rectangular pulse electrodeposition technique was applied. Y2O3 was formed during the electrodeposition, and Y2O3:Eu (III) film was formed also in DMF containing YCl3, EuCl3 and a small amount of water.

Fabrication‐Driven Oxidation Pathways in Y/Hf‐Modified High‐Entropy Alloys: From Elemental Segregation to Oxide Homogeneity

Rare Metals, EarlyView.
ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Effect of the heating rate and Y2O3 coating on the microstructure of Wf/Y2O3/W composites via field assisted sintering technology

Nuclear Materials and Energy
Field assisted sintering technology (FAST) is one of the potential methods to fabricate tungsten fiber reinforced tungsten (Wf/W) composites. The microstructure and mechanical properties of Wf/W composites are closely related to the sintering parameters.
