3.  Transparent electronics is an emerging
science and technology that concentrates on
producing transparent electronic circuits.
 The application contains consumer
electronics such as automobile windshield,
transparent solar panel, transparent display
etc.
 The goal is to create an invisible circuitry
with materials that are optically transparent
and electrically conductive.

4.  The transparent electronics were pioneered
at the Oregon state university. Researchers
of the Oregon State University confirmed
that zinc tin oxide, an inexpensive and
environmentally benign component can
provide a new transparent technology where
computer memory would be based on
resistance instead of electron charge.
 The products that use resistive random
access memory(RRAM) OR memristor could
become even smaller an faster.

5.  Transparent conductors are neither 100%
optically transparent nor metallically
conductive.
 a transparent material is an insulator which
possesses completely filled valence and
empty conduction bands.
 Whereas metallic conductivity appears when
the Fermi level lies within a band with a
large density of states to provide high

7.  SnO2, ZnO and CdO are the commonly used
oxides.
 These TCO hosts must be degenerately
doped to displace the Fermi level up into the
conduction band.
 ZnO films have been prepared by doping
with Group III (Al, Ga, In and B), Group IV
(Si, Ge, Ti, Zr and Hf) and a Group VII
element (F substituted at an oxygen site),

8.  Degenerate doping provides
(i) the high mobility of extra carriers
(electrons)
(ii) low optical absorption due to the low
density of states in the conduction band.
 Removal of oxygen.

9.  Transparent conducting oxides
They are electrically conductive
materials with low absorption of light.
 The transparent oxides have high
transparency through the visible
spectrum.
 It is a compromise between electrical
conductivity and optical transparency.

11.  The Burstein–Moss
effect is the
phenomenon of which
the apparent band
gap of a
semiconductor is
increased as the
absorption edge is
pushed to higher
energies as a result
of all states close to
the conduction band
being populated.

14.  A thin film transistor is a special
kind transistor that is formed by
depositing thin films of an active
semiconductor layer as well as
dielectric layer and metallic
contacts over a supporting
substrate (usually non conducting
[glass]).

16.  They operate at relatively low frequency.
 They exhibit linear or near linear
characteristics.
 The parasitic capacitance is minimum.

17.  A film capacitor is a capacitor that uses a
thin film as the dielectric.
 They are relatively cheap, stable over time
and have low self inductance.
 Large capacitance density is desired to
minimize the size of the capacitor. Hence
materials with high dielectric constants are
the best.

19.  Expected to behave in a non-ideal
manner.
 The main reason for this
characteristics is,
The relatively poor conductance of
TCOs compared to metals, TTFIs will
possess a significant amount of
parasitic resistance.

24.  Visible transparency
 Low cost (solution based
deposition and printing).
 Low temperature processing.
 Robust, stable inorganic
materials.
 Safe and non toxic materials.

25. High resistance of TCOs
Low frequency of
operation(Khz to few Mhz)
 transparent electronics
cannot be realized in Si
technology.

26. Touch display panels.
Solar cells
Heaters.
Defrosters.
Optical coating and many
more.

31.  Transparent electronics is a
boon to the technology
 This will help in the development
of flexible non breakable
materials.
 Holds the key for many future
advancements in efficient usage
of energy.
