3. INTRODUCTION
• Organic electronics is a branch of
electronics.
• It deals with conductive polymers and
conductive small molecules.
• Most polymer electronics are laminar
electronics.
• Conductive polymers are lighter, more
flexible, and less expensive.
• This makes them a desirable alternative
in many applications.
• They are not well structured.

4. CONDUCTIVE ORGANIC
MATERIALS
• Conductive Organic Materials can be grouped into two
main classes:
Conductive Polymers and Conductive Small
Molecules.
Conductive small molecules are usually used in the
construction of organic semiconductors, which exhibit
degrees of electrical conductivity between those of
insulators and metals.

5. ORGANIC VS. INORGANIC
ELECTRONICS
ORGANIC
• It is amorphous is
structure.
• It’s processor can maintain
low temperature.
• It has high flexibility.
• It’s stability is currently an
issue.
INORGANIC
• It is single crystalline in
structure.
• It’s processor becomes
heated pretty quickly.
• It has very low flexibility.
• It is very stable.

6. ADVANTAGES AND
DISADVANTAGES
Advantages:
• Technology is compatible with Large area processes (low cost)
• Low temperature processing (low cost)
• Molecules and polymers can be tailored for specific electronic or optical
properties
• Compatible with inorganic semiconductors
Disadvantages:
• Low carrier mobility
• Electronic and optical stability of the materials
• Processing is incompatible with classical processing in semiconductor
industry.

7. APPLICATIONS OF ORGANIC
ELECTRONICS
• Organic Vapor Phase Deposition (OVPD)

9. OVPD
• OVPD was invented by Professor Steve Forrest at
Princeton University has potential to overcome the
limitation of VTE
• The arrangement of evaporation and condensation is
decoupled
• Evaporation of the organic material occurs in individual
and decoupled quartz pipes.
• A precise amount of carrier gas is added into each
quartz pipe by MFC to pick up organic molecules.
• Then it’s transported into hot wall deposition chamber
• They (ex: host and dopant) mix and evaporate.
• They diffuse through the boundary layer on to the
cooled substrate

10. OLED(ORGANIC LIGHT
EMITTING DIODE)
OLED is a flat light emitting technology, made by placing a
series of organic thin films between two conductors. when
electrical current is applied, a bright light is emitted.
OLEDs can be used to make displays and lighting.
Because OLEDs emit light they do not require a backlight
and so are thinner and more efficient than LCD
displays(which do require a white backlight).
• First developed in early 1950’s.
• Multiple organic layer sandwiched between two electrodes
marked as cathode and transparent anode.
• Principle: Electroluminescence(It is a characteristic of a
material, typically semiconductor which enables it to emit
light and response to an electrical current or strong
electrical field).
• Doesn’t require any backlight, self emitting.

11. OLED VS. LCD

13. OFET(ORGANIC FIELD-EFFECT
TRANSISTOR)
An Organic Field Effect Transistor(OFET)is an

be prepared either by vacuum evaporation of
small molecules by solutions casting of polymers
or small molecules,or by mechanical transfer of a
peeled single crystalline organic layer onto a
substract.These devices have been developed to
realise low cost, large area,electronic products
and bio-degradable electronics.
