Solar Cells:GaN’s wide band gap covers the solar spectrum from 0.65 eV to 3.4 eV (which is practically the entire solar spectrum), making indium gallium nitride

(InGaN) alloys perfect for creating solar cell material. Because of this advantage, InGaN solar cells grown on GaN substrates are poised to become one of the most important new applications and growth market for GaN substrate wafers.

Ideal for HEMTs, FETs

GaN Schottky diode project: We accept custom spec of Schottky diodes fabricated on the HVPE-grown, free-standing gallium nitride (GaN) layers of n- and p-types.

Both contacts (ohmic and Schottky) were deposited on the top surface using Al/Ti and Pd/Ti/Au.
