--------------------------------------------------------------------------------------------------------------
Zinc Oxide (ZnO) can be grown as a single crystal semiconductor with very interesting properties.
The bandgap is in the 3.4 eV range which makes it attractive for many of the blue and violet applications
in opto-electronics as well as UV devices. It is available in bulks, in wafers of up to 2 inches,
which gives it a major advantage over Gallium Nitride and other group III Nitrides.
ZnO also has the potential to become the substrate material of choice for GaN. Like GaN it has a wurtzite structure, with lattice constants closely matched to GaN (a=3.249, c=5.205). ZnO is exactly
lattice matched to InGaN with a 22% In content. Perhaps most importantly it is a soft compliant material
that is believed to probably and may take up the lattice stress in preference to the growing GaN layer.
It suffers from the drawback that it dissociates in ammonia at temperatures above 600°C. With its wide bandgap, Zinc Oxide could prove very useful in optical applications as well as many high speed electronics.
ZnO may also be used as a substrate for epitaxial growth.
Application:
Zinc oxide (ZnO) crystal substrateProduct Description:Zinc oxide (ZnO) crystal substrate is widely used in
GaN (blue LED) epitaxial substrate, broad band connecting devices and other fields.Technical parameters
