Abstract
Zinc Oxide (ZnO) is emerging as a material of interest for a variety of
electronic applications. It can be used in a large number of areas and unlike
many of the materials with which it competes ZnO is inexpensive, relatively
abundant, chemically stable, easy to prepare, and non-toxic. Most of the
doping materials that are used with ZnO are also readily available.
At present, the most widely publicized application for ZnO is as an ITO
replacement for displays and photovoltaic panels, where ZnO could lower costs
of transparent conductors. But new applications for ZnO are much broader than
that. ZnO is not just a conductor, but can be used as a semiconductor capable
of making inexpensive transistors for disposable electronics or even low-cost
LEDs. ZnO may also find applications in thin-film batteries and ZnO' s ability
to be engineered into interesting nanostructures hint at new applications down
the road. ZnO is already being tapped in spintronics.
There remain technical difficulties that still need to be worked out if ZnO is
to achieve its full potential. One important one is that there is as yet, no
p-type ZnO semiconductor. Yet the number of patent filings of ZnO uses in
electronics continues to grow and NanoMarkets believes that ZnO will represent
a substantial market as an electronic material over the next eight years. With
this in mind, NanoMarkets is publishing a new report which identifies and
quantifies the opportunities for ZnO in the electronics sector.
