Our company produces single-crystal gallium oxide using the melt growth method "EFG" (Edge-defined Film-fed Growth method) with most stable β-type crystal structure.Applications
1) Substrate for Visible / Ultraviolet LED
Vertical LED structure by "transparent and conductive" characteristics of Gallium oxide substrate.
2) Substrate for Power semiconductor
High-breakdown Voltage and Low-Loss devices by "Large band gap energy" characteristics of Gallium oxide substrate.
3) Ultraviolet detector
Ultraviolet detectors can be designed without the optical filter.
