TRANSPARENT ELECTRONICS

Introduction to TE

• Invisible electronic circuitry

• Opto electronic devices

• Glass in any setting can be used

Goals of TE

• Main goal is to build a high performance transparent electronic devices

• Implementation and evaluation in transistors and circuit structures

• Achieving application specific properties

Optical transparency with electrical conductivity

• Achieving conductivity in transparent materials is difficult

• Structural relaxation around the impurities is preferred for a non rigid band shifting of fermilevel

Electronic properties of conventional TCO’s

Carrier generation in conventional TCO’S

• Substitutional doping

• Oxygen reduction

Transparent electronic devices

MATERIALS DEVICES CIRCUITS SYSTEMS

Passive linear devices used

• Resistors

• Inductors

• capacitors

Transparent thin film transistors

• Heart of the system

• N channel TTFT’s are used here

• Magnitude of drain current depends on gate over voltage

applications

• Can be used to replace all the real time opaque electronic equipments and home appliances
