There is increasing work on printed inorganics as people struggle with the
performance of organics in some aspects. For conductors with vastly better
conductance and cost, for the best printed batteries, for quantum dot devices
and for transistor semiconductors with ten times the mobility, look to the new
inorganics. That is the emerging world of new nanoparticle metal and alloy
inks that are magnitudes superior in cost, conductivity and stability, such as
the flexible zinc oxide based transistor semiconductors working at ten times
the frequency and with best stability and life, along with many other
inorganic materials. Read the world's only report that pulls all this together
in readable form.
This report critically compares the options, the trends and the emerging
applications. It is the first in the world to comprehensively cover this
exciting growth area. The emphasis is on technology basics, commercialisation
and the key players.
This report is suitable for all companies developing or interested in the
opportunity of printed or thin film electronics materials, manufacturing
technologies or complete device fabrication and integration.
IDTechEx forecasts a market of $45 Billion for printed electronics by 2022 and
that market is expected to be more or less evenly divided between organic and
This report reveals the rapidly increasing opportunities for inorganic and
composite chemicals in the new printed electronics, given that so much of the
limelight is on organics. Inorganics encompass various metals, metal oxides as
transparent conductors (such as fluorine tin oxide or indium tin oxide,
extensively used in displays and photovoltaic technologies) or transistor
materials as well as nano-silicon or copper and silver inks, whether in
particle or flake form. Then there are inorganic quantum dots, carbon
structures such as graphene, nanotubes and the various buckyballs etc.
However, there is much more, from light emitting materials to battery elements
and the amazing new meta-materials that render things invisible and lead to
previously impossible forms of electronics.
Over the next ten years, improvements in inorganic conductors such as the use
of nanotechnology and the lack of improvement of the very poorly conductive
and expensive organic alternatives means that inorganics will be preferred for
most conductors whether for electrodes, antennas, touch buttons, interconnects
or for other purposes. By contrast, organic substrates for flexible
electronics such as low cost polyester film and paper will be preferred in
most cases because they are light weight, low cost and have a wide range of
mechanical flexibility. The use of inorganic substrates such as glass
represents a fall-back particularly required where there is failure to reduce
processing temperatures. Here stainless steel foil printed reel to reel is an
improvement, where possible.
The report considers inorganic printed and thin film electronics for displays,
lighting, semiconductors, sensors, conductors, photovoltaics, batteries and
memory giving detailed company profiles not available elsewhere. The coverage
is global - with companies from East Asia to Europe to America all included.
The application of the technology in relation to other types such as organic
electronics and silicon chips is given, with detailed information clearly
summarised in over 160 tables and figures.
Elements being targeted
In order to meet the widening variety of needs for printed and potentially
printed electronics, not least in flexible, low cost form, a rapidly
increasing number of elements are being brought to bear. Oxides, amorphous
mixtures and alloys are particularly in evidence. Even the so-called organic
devices such as OLEDs variously employ such materials as B, Al and Ti oxides
and nitrides as barrier layers against water and oxygen, Al, Cu, Ag and indium
tin oxide as conductors, Ca or Mg cathodes and CoFe nanodots, Ir and Eu in
light emitting layers, for example.
This report is essential for all those wishing to understand this technology,
the players, opportunities and applications, to ensure they are not surpassed.
