Transparentelectronics
What is transparent electronics ?Transparent electronics is an
emerging technology that employs wide band-gap semiconductors for
the realization of invisible circuits.
Domestic Appliance
Transparent mobile
A New era
Transparent conductive film of graphene.Structure of
graphene
They are so small that cannot be distinguished by eyes.
Transparent Battery
"The clear flexible plastic in the image is a battery, which is
just 1atom thick.
The power rate performance is strikingly high it only takes one
minute to fully charge the battery and it has a long cycle life,
often exceeding 1,000 cycles."
Advantages of Transparent electronics
Nontoxic elements and cheap materials
Cheap processing and mass production
Band gap energy with high mobility

transparent USB memory drive: Polytron Technologies has produced
a transparent USB memory stick that will come in 8, 16 & 32GB
options. The USB has an embedded LED so that you know that it is
connected and working.
ITO: Indium $92/kg(2002) $930/kg(2013) Can only satisfy the
demand till 2028 (Source: American Mining Association 2013) Indium
is toxic! Graphene: Carbon. Can be found everywhere, very cheap,
non-Toxic.
Why graphene ?
Graphene is flexible & strong
ITOITO is a ceramic material, poor flexibility

best material for the channel (semiconductor) in TTFTs.
Aligned Nanotubes
Transfer printing of aligned nanotubes enabling low T
fabrication
Key features: 1. Low T 2. Keeping alignment 3. Repeatable 4.
Scalable @5. compatible with graphene
Carbon nanotubes are made by several methods
Chemical Vapor Deposition (CVD)arc dischargelaser ablationHIPCO:
Hi-pressure carbon monoxidesurface mediated growth of
vertically-aligned tubes by Plasma Enhanced Chemical Vapor
Deposition (PECVD)

Transparent RAM
TRRAM device is based on an capacitor structure which provides a
transmittance of 81% in the visible region of the chip. the data
retention is expected to be about 10 years.
