Introduction
 In Transparent electronics the usual
opaque semiconductor materials forming
the basis for electronic device fabrication
is replaced with Transparent materials.
 Transparent electronics is an emerging
technology that employs wide band-gap
semiconductors for the realization of
invisible electronics circuits and optoelectronics devices.

There are two technologies which preceded and
underline transparent electronics:1.Transparent Conducting Oxides(TCOs)
2.Thin Film Transistors(TFTs)

1. Transparent Conducting
Oxides(TCO)
• TCOs constitute an unusual class of materials possessing
two physical properties (generally considered mutually
exclusive)
1.High Optical Transparency(e.g>3.1eV)
2.High Electrical Conductivity
The three most common TCOs are indium oxide In2O3 tin
oxide SnO2 and zinc oxide ZnO2

2. Thin-Film Transistors
(TFTs)
• A thin-film transistor (TFT) is a special kind of fieldeffect transistor made by depositing thin films of an
active semiconductor layer as well as the dielectric
layer and metallic contacts over a supporting (but nonconducting) substrate.

• Channel is formed from highly insulating,
wide band gap transparent semiconductor
(ZnO)
• Two possible configuration:i. Bottom gate
ii. Top gate

Graphene
• Graphene is an allotrope of carbon in the form of
a two-dimensional, atomic-scale, honey-comb
lattice.
• It is the basic structural element of other
allotropes, including graphite, charcoal, carbon
nanotubes and fullerenes.
• . It conducts heat and electricity efficiently and is
nearly transparent.
• Graphene is simply one atomic layer of graphite a layer of sp2 bonded carbon atoms arranged in a
hexagonal or honeycomb lattice.
• Graphene has unique properties that exceed
those of graphite.

 Graphene is the strongest material ever found; it
is more than 40 times stronger than diamond.
 Graphene is more transparent conducting film
over, Indium because Carbon is more cheaper,
easily available and also non-toxic.
